Buying an amp online

Worried about buying an amp online without playing it first? You needn’t be. Online music instrument retailers like Thomann, Sweetwater and Sam Ash offer hassle-free returns as standard, so you can purchase an amp, play it in the comfort and privacy of your home and, if it’s not for you, send it back with ease. Check the specific returns policy for your chosen retailer before you purchase, but most offer between 30-45 days to return an item, as long as it’s in original condition.

Buying the best guitar amp for you is pretty much the toughest gear decision any player will make. Finding your next guitar is not easy either, but there’s something about a guitar that lets you know it’s the right one. An amplifier? There’s just too much to consider.

Finding the right amp is crucial. Bad guitars can sound incredible through great amps, but a duff amp will make a great guitar sound bang average. Not only that, but an amplifier’s tones and its response can really make the difference with your playing. Our advice? If you find an amp that you get along with, don’t let it out of your sight. 

Here we've got 17 of the best guitar amplifiers you can buy today, listed in price order to help you choose the right amp for your budget. We’ve got something for all styles here, amps for all occasions and in a variety of formats, from high-powered amp heads to combos and super-portable pedalboard options, and we’ll be looking at some of the considerations you should make when choosing your next amp.

With Amazon Prime Day on the horizon in October, it could be worth waiting a little longer to pick up a guitar amp bargain. If you can wait a little longer, we’ll be sharing all the best bargains on our Prime Day music deals page.

What is the best guitar amp right now?

We’ve actually got two top picks right now. The Fender ’68 Princeton Reverb offers some of the sweetest Fender tones you’ll hear. Tune in for pristine, shimmering cleans that break up nicely, with onboard spring reverb and tremolo to sweeten your tone further. It’s ideal for small gigs, recording and manageable enough for the home – especially if your dirt comes via a pedal.

The Victory VC35 The Copper is a single-channel, 35-watt lunchbox head serving up a sumptuous smorgasbord of rock and blues tones – the VC35 has got the sort of performance that invokes the “B” word. With an EL84 power section and a NOS EF184 pentode the flavour is very much British, with that winsome musical chime that calls to mind vintage Vox amps. Lovely.

Head, combo, pedalboard: which format is right for you?

The question of head versus combo has been complicated in recent years by the dawn of the pedalboard amp – a guitar amp that’s housed in an enclosure the size of a small multi-effects, yet often powerful enough to replace your amp head.

With a pedalboard amp, the benefits are obvious. You can throw it in your backpack and off you go. They can also be incredibly versatile, with the likes of the four-channel format of BluGuitar’s Amp 1 offering a lot of tones for its size and price.

But it all depends on how important portability is to you. The traditional amplifier head, which you would then hook up to an external speaker cabinet, remains a hugely appealing prospect, particularly if you have a speaker cabinet already at home, and if you pay for rehearsal space at a studio they’re sure to have a cabinet you can use there.

The combo is an amplifier and speaker all in one package. Size matters. A small combo with a single 10-inch speaker can still be a significant burden to cart around, but for many of us, the convenience of having an all-in-one setup is too good to pass up, especially if we’re going to keep it at home.

Valve amplifiers vs solid-state and digital amps

There will forever be tension between the desire for old-school valve amp tone and the ever-dependable reliability of a solid-state amplifier that uses transistors, diodes and so forth to amplify your signal. 

This is further complicated by digital modelling technology that allows amplifiers to mimic the tonal characteristics and response of other styles of amplifiers.

You might well ask why the modelling amp isn’t the no-brainer choice here. After all, valve amps need servicing over time and you’ll invariably need to replace the valves at some stage. Furthermore, to get the valve amp sounding at its best it’ll typically need to be played at the upper limits of its capabilities – bad news for domestic and neighbourly bliss. They’re also heavier.

We don’t talk enough about how we need to learn how to play the amplifier

But then, with most of the R&D hours spent refining solid-state amplifier technology and developing digital modelling processors to replicate genuine valve amp tone, why not go straight to the source? Also, with many low-powered valve amps on the market, you have options for the home.

There is no right answer, but it is worth bearing in mind that the gap between valve amp and digital tone is getting closer.

We said at the start that finding the best guitar amp for you is tough, and it is. We don’t talk enough about how we need to learn how to play the amplifier  – how to dial in the tones that suit us, and to tailor our playing accordingly for them.

Every amplifier will have its own response. Some amplifiers are unforgiving, with frequencies poking out when you don’t want them to, amplifying your mistakes and punishing sloppy playing, yet those same amplifiers can make an expert player’s chops really pop out.

Our list features amps from both sides of the spectrum. The true test of which is better is what sounds better to you, and what suits your playing style. As ever, that is all that matters.

Best guitar amps: Positive Grid Spark 40

1. Positive Grid Spark 40

The ultimate smart guitar amplifier

Price: $299 | Type: Modelling desktop amp | Output: 40W | Valves: N/A | Number of channels: 30 Amp Models | Speaker: 2x4” custom designed | Weight: 5.2kg | Key Features: BIAS Tone Engine and app integration for jamming, 40 effects, headphones out, Bluetooth, USB, four programmable presets, tuner, Auto Chord, Smart Jam

Packed with features
Comprehensive range of tones
Smart Jam and Auto Chord features are invaluable for practice and learning
Waiting times on orders can vary

Where to start with the Spark 40? Well, it just stops short of cooking your dinner, but it has most other essential functions covered – and a few more besides. Its core centres around Positive Grid’s BIAS Tone Engine modelling tech, which allows it to put together a formidable collection of amp models and cover all bases tone-wise.

Altogether are 30 amp models to choose from, and 40 effects, so it’s punching big numbers already in the context of desktop amp functionality, but with the accompanying app, the Spark offers a transformative experience. It may well change how you think about guitar amplification.

The Spark’s Smart Jam feature allows you to play some chords or a riff and the amp will generate a backing track for you to play to. Who needs friends? Auto Chord allows you to stream music from your mobile device to the Spark and it will transpose the chords so you can play along. As a learning and practice tool, it doesn’t get much better. 

There are outputs for recording and silent practice. Sure, it’s 100 percent digital, but it feels analogue, and crucially it sounds great at low volumes. When you crank the Spark, its dual 4” speaker setup fills the room with a sound that has no right to be so three-dimensional.

Early adopters of the Spark have experienced some shipping delays, but things appear to be improving rapidly. Check here for the latest updates on shipping times.

Best guitar amps: Yamaha THR30 II Wireless

2. Yamaha THR30 II Wireless

A fully wireless desktop amp that you can take anywhere

Price: $499/£419/€479 | Type: Battery-powered desktop combo | Output: 30W (2x 15W stereo, 15W battery) | Valves: N/A | Number of channels: 15 Amp Model Combinations, Acoustic Mic Models, Bass Amps, Flat Voicings | Speaker: 2x 3.5 | Weight: 4.3kg | Key Features: 15V DC power supply / internal rechargeable battery, headphones output, USB, 2x 1/4” line out, spring and hall reverbs, effects (chorus, flanger, phaser, tremolo, echo, compressor, noise gate), THR Remote App, bundled Cubase AI, full wireless capability

Take it anywhere!
Ideal for practice and home recording
Easy to operate
The plastic backing is lightweight but not very “guitar amp”

Yamaha’s THR series remains groundbreaking. It looked to dress the guitar amplifier in home audio stylings, pack it with digital functionality that – crucially – was rooted in the feel and response of valve amplifiers, and make it portable.

Well, amps don’t get much more portable than the THR30 II Wireless. It can be operated via the 15V DC power supply, or, alternatively, charge it up and take it out with you to enjoy 15 watts of stereo solid-state power in the park, by the beach, on top of a skyscraper a la U2. Whatever you like.

It is bundled with Cubase AI, has a very respectable complement of onboard effects, and with headphones and USB outputs it is a sound option for home recording and late-night practice sessions. It also looks so good you could leave it in the living room without getting a ticking off.

Best guitar amps: Blackstar Silverline Deluxe head

3. Blackstar Silverline Deluxe head

A boutique take on digital modelling amp tech

Price: $529/£449/€499 | Type: Digital modelling head | Output: 100W at 4ohms | Valves: N/A | Number of channels: 6 fully-programmable voices, 12 onboard memory slots | Speaker: N/A | Weight: 9.6kg | Key Features: Patented TVP output stage emulation, patented ISF EQ shift, built-in tuner, USB for direct recording remote control and firmware updates via Insider software app. Emulated headphones/recording out and mp3/line in (can be switched to effects loop send/return using Insider software), MIDI in, Matching 2x12” cab

Great set of features
Lightweight and classy build
Excellent options across the range
Well laid-out front panel
Alternatives offer more effects options

When Blackstar launched its Silverline series, it was as though digital modelling amplifiers had grown up, bought their first suit and got a real job. The “B” word was invoked, and with good reason, because the grey-silver on grey designs, the feature-set, the seriousness, make everyone stop for a minute and consider their options.

With the Silverline, there are many. If you like the idea of the Silverline but aren’t looking for a head, the range also includes the 20W Standard 1x10”, the 50W Special 1x12”, the 100W Deluxe 1x12”, and the 2x100W Stereo Deluxe 2x12” combos.

The setup and look on each is similar, with Blackstar's SHARC processing tech under the hood to keep the tones legit. There are effects, programmable settings, and TVP tech allowing you to select the power-tube emulation you prefer. They look and sound like real valve amps, but have all the mod cons that tomorrow’s player needs today. Credible, convincing, state-of-the-art.

Best guitar amps: Boss Katana Artist MkII 1x12”

4. Boss Katana Artist MkII 1x12”

A fully-featured digital modelling combo amp

Price: $599/£569/€649 | Type: Modelling combo | Output: 100W switchable to 50W or 0.5W | Valves: N/A | Number of channels: 5 amp types w/two modes each | Speaker: 1x 12" Custom Waza Speaker | Weight: 23.6kg | Key Features: 3x digital reverbs 5x Simultaneous Effects (Delay,Tremolo, Flanger, Pitch Shift, Phaser, Wah), mic’d cab emulation, over 60 effects downloadable via Boss Tone Studio, Series/Parallel Effects Loop, MIDI in, USB, headphones output

Superb suite of contemporary features
Goes from super-clean to high-gain
Onboard effects are excellent
A little more expensive than its MkII Katana kin

The Katana series has been a front-to-back triumph for Boss, packing a handful of amp models into small formats, loading them up with onboard effects and a heap of contemporary features and making them available at an accessible price.

This Artist MkII combo is the flagship model, and while we’d happily endorse any of the Katana MkII amps, the additional MIDI functionality and an upgraded Waza Craft speaker is a big selling point.

For a digital amplifier, the front panel is reassuringly familiar. Think of it as a five-channel amplifier, with five amp modes, but with two modes on each model it expands your tone options dramatically. This will do bell-like cleans, searing high-gain chug, and all in between, and with Boss’s Tube Logic architecture, it all feels and sounds convincing. The onboard effects are top-grade and you can get more online via the Tone Studio library. There’s a rabbit hole to fall into, but chasing usable tones is a breeze.

Best guitar amps: Blackstar HT-20R MkII

5. Blackstar HT-20R MkII

A flawless, feature-stacked combo at an accessible price

Price: $599/£649/€729 | Type: Valve combo | Output: 20W (switchable to 2W) | Valves: 2x ECC83 preamp valves, 2x EL84 power amp valves | Number of channels: 2 | Speaker: 1x 12” | Weight: 16.2kg | Key Features: 2-button footswitch, reverb, XLR DI out, USB out

Impossible to fault at this price
Footswitchable overdrive voicings
Digital reverb is excellent
A fine tone range, from clean to high-gain
None at the price

Offering plenty of change from a grand, Blackstar’s HR-20R MkII is a mid-priced valve combo that does a very good impression of an amp retailing at two or three times the price. It is a two-channel amp with footswitchable overdrive voicings, and an uncanny ability to play the field tonally.

The clean channel is a simple affair with a solitary tone control and a volume, with modes for scooped US tone – think Fender et al – and a quintessentially British mode with tight mids and treble chime. 

You could get lost in the cleans, adding a splash of reworked digital reverb that now sounds studio-quality. But don’t forget you’ve got an overdrive channel with Classic and High Gain voicings that will take you from classic ‘70s rock crunch through to contemporary metal. And all this from one package. It’s loud enough for the stage but you can power down to 2 watts for bedroom shredding. It’s a remarkable feat of amp building.

Best guitar amps: Fender Blues Junior IV

(Image credit: Fender)

6. Fender Blues Junior IV

The best low-price combo for all-valve blues tones

Price: $599/£609/€659 | Type: Valve combo | Output: 15W | Valves: 3x 12AX7 preamp valves, 2x EL84 power amp valves | Number of channels: 1 | Speaker: 12" Celestion A-Type | Weight: 14.3kg | Key Features: Op-amp-driven spring reverb, Fat switch

Ace clean tones and hot sizzling drive
Fat switch thickens up single-coils nicely
Lacks clean headroom when playing with a drummer

There is a reason why the Blues Junior tops the best-seller charts for valve-amp combos. Its USP is putting classic Fender tones into a super-affordable package that’s portable, fuss-free and is tooled for our present moment where we want great tube tones at low volumes and pedalboard compatibility.

But even before you bring your ‘board into play, the tight low-end and sparkling high-end of the Blues Junior will put a spell on you. The FAT switch is an act of modest genius, doing exactly what you’d imagine it would, widening the frequencies and adding a beer gut to your single-coil tone.

The FAT switch is really the only thing you’ll find on the control panel that requires explanation, otherwise the Blues Junior is just a straight-up, fuss-free combo, and, dare we say it, a modern classic. Drive it hard and you’ll enter blues-rock nirvana.

Best guitar amps: BluGuitar Amp1 Mercury Edition

7. BluGuitar Amp1 Mercury Edition

A truly game-changing pedalboard amp

Price: $799/£669/€633 | Type: Pedalboard amp | Output: 100W switchable to 5W | Valves: Sub-miniature Russian twin triode | Number of channels: 4 | Speaker: N/A | Weight: 1.2kg | Key Features: Nanotube tech, digital reverb, effects loop, MIDI in, footswitch input (Remote1 footswitch sold separately), speaker-emulated line-out

Portable, powerful and versatile
Four-channel setup offers heaps of options
Next-level digital spring reverb
Remote1 MIDI footswitch is pricey

Like the best innovations in guitar technology, the Thomas Blug’s Amp1 keeps all the clever stuff hidden from sight, allowing players to concentrate on what is frankly difficult enough – playing the guitar.

But the Amp1 really is clever. It’s the size of a multi-delay unit, you can throw it in a bag and take it wherever, and yet offers you four channels, 100W of Class D power, with some analogue mojo fairy dust by way of a sub-miniature Russian twin triode.

Simply select which channel you want – Clean, Vintage, Classic, Modern – and dial in your tone via the 3-band EQ and volume, master and gain controls. It’s just like a real amp, and that’s the point – it is. This is the shape of amps to come. 

Partner it with the Remote1 footswitch you can access all four channels, boost and reverb via MIDI, plus add an ancillary master volume and adjustable power soak. You can save your settings down and use them as you might in a pedalboard. This is a futuristic amp for those squeamish about apps, software and digital sterility.

Best guitar amps: Victory V4 The Duchess Pedal Amp

(Image credit: Victory)

8. Victory V4 The Duchess Pedal Amp

Super-sweet low-gain boutique tones with heaps of power

Price: $799/£699/€839 | Type: Pedalboard amp with Class D power stage and valve-driven preamp | Output: 180W at 4ohms | Valves: 1 x EC900, 3 x CV4014 preamp | Number of channels: 1 | Speaker: N/A | Weight: 1.6kg | Key Features: Digital reverb, tremolo, series effects loop, balanced line out, DC power outlet

Super-portable
Abundant headroom and sparkling cleans
Very musical reverb and tremolo
Fan is always-on, making recording tricky

The Duchess Pedal Amp assumes a similar form to Victory’s V4 series of pedal preamps, but it’s a fully functioning amplifier with a whopping Class D power stage that delivers 180 watts at 4 ohms, and a truly lush valve-driven preamp that makes damn sure you don’t mistake this as just some kind of practical option for the gigging musician. 

Sure, it is practical, but it is the tones that will have the hair on the back of your neck standing to attention. Specifically, clean tones, and with a boutique low-gain tone profile like that, it should come as no surprise that the Duchess just loves overdrive pedals. 

The enclosure is super-tough, powder-coated steel, with its complement of chickenhead knobs protected by a raised steel kick bar. A single footswitch turns the tremolo on and off. For itinerant players, this could be the ultimate amp.

Best guitar amps: Fender ’68 Princeton Reverb

9. Fender ’68 Princeton Reverb

The best all-valve combo you can buy

Price: $899/£969/€1,179 | Type: Valve combo | Output: 12W | Valves: 3 x 12AX7, 1 x 12AT7 | Number of channels: 1 | Speaker: 10" Celestion | Weight: 15.7kg | Key Features: Dual inputs, tremolo, valve-driven reverb

Loud enough for small gigs
Sparkling cleans, hot sizzling drive
Heavenly spring reverb and lush tremolo
Takes pedals well
Look elsewhere for high-gain

The Fender Princeton Reverb has long been considered the Goldilocks option for those looking for an all-valve combo with manageable volume, but one that’s loud enough for small shows.

There is a reasonable amount of headroom on offer, with its bell-like cleans mother’s milk to blues and country players, and as you crank up the volume you’ll find a gritty breakup that’s warm, musical and addictive.

This ’68 reissue comes with the silver-panel and aluminium grille cloth trim. Under the hood it has been tweaked by Fender so it will take pedals better, with negative feedback reduced to enhance its response and bring on overdrive that little bit quicker. Under the hood you’ll find hand-wired valve sockets and custom-made Schumacher transformers. The tube-driven reverb and tremolo is divine.

Best guitar amps: Vox AC15C2

10. Vox AC15C2

A classic British combo in 2x12 format

Launch price: $899/£725/€799 | Type: 2x12 tube combo | Output: 15W | Tubes: 2x EL84, 3x 12AX7 | Number of channels: 2 (not footswitchable) | Speaker: 2x Celestion G12M Greenback 12" | Weight: 30.2kg

Usable volume
Classic tones
Responds well to pedals
May not be enough headroom for totally clean players

The new-ish AC15 'Twin' retains the all-important dual-EL84, cathode-biased output section of its forebear, but otherwise it's very different. A quick scan across the top panel reveals two inputs for independent access to either normal or top boost channels. 

One benefit of the bigger, 2x12 enclosure is that it provides ample room for a full-length reverb tank, housed in the bottom. There's also an in-built tremolo effect, with controls for depth and speed. 

But the whole point of this amp is the pair of 25-watt Celestion G12M Greenback speakers. They are the speaker of rock in so many cases and while purists might hope for Celestion Blues, they would add a fair amount to the price; and the increased power handling of two Greenbacks on the end of just 15 watts is quite a tantalising prospect. 

It's fair to say that even with the master volume set-up, the magic doesn't really start happening until the amp's lungs are at least half way open, but happily, that's not far from perfect for many of today's pub and bar gigs – it may even be too much for some.

Best guitar amps: EVH 5150III 50W EL34

(Image credit: EVH)

11. EVH 5150III 50W EL34

The best valve head for hard rock and metal

Price: $1,099/£1,149/€1,990 | Type: Valve head | Output: 50W at 4ohms | Valves: 8x JJ ECC83 preamp valves, 4x JJ EL34 power amp valves | Number of channels: 3 | Speaker: N/A (matching 2x12 cab £479) | Weight: 15.9kg | Key Features: Series effects loop, headphones out, preamp out, MIDI input, external bias adjustment, Resonance control for cab matching

A compact powerhouse with gain to burn
Exceptional harmonic and dynamic detail
MIDI switchable channels and effects loop
A lot of volume for domestic use

Sometimes you have to split the atom with a saturated level of gain that would violate health and safety in pretty much all other contexts, and that’s an occasion where you’d hope to find the EVH 5150III on the backline.

This amp bears Edward Van Halen’s initials on the front, so take it as read that you can access that harmonically volatile weekend rock tone, but dime the lead channel and you’ll have all the gain you need for contemporary metal too. 

And yet, there’s subtlety and complexity to be found here – even at the extremes. The 5150III’s gain is rich in harmonics. It is dynamic, and with the EL34 power tubes it takes on the tonal character of a hyper-trophied Marshall Plexi. This is guitar tone as spectacle, a roman candle of overdrive with a very usable clean channel.

Best guitar amps - Orange Rocker 32

(Image credit: Orange)

12. Orange Rocker 32

A killer combo for pedal users – especially stereo fans

Price: $1,099/£849/€1,045 | Type: Stereo tube combo | Output: 30W, switchable down to 15W | Number of channels: 2 | Tubes: 4x EL84, 4x ECC83, 2x ECC81 | Speaker: 2x Orange Voice Of The World Gold Label 10" | Weight: 23.3kg

True stereo capability
Great for pedal users
Deceptively versatile
Could do with side handles for portability

The Rocker 32’s secret weapon is its stereo capabilities courtesy of two output stages and a mono out/stereo in valve-buffered effects loop – and it’s this that opens the door to some tantalising effects possibilities. It also features a half-power option incorporated into the front panel standby switch. 

The enamel control panel follows Orange’s classic 1970s ‘graphics only’ format, using pictograms to describe the control functions. The Dirty channel includes gain, bass, mid, treble and master volume controls, while the clean Natural channel has a single volume control. The Natural channel may only have a single volume control, but it’s perfectly dialled in to flatter practically any guitar and it sounds wonderful, with a glassy treble giving way to an addictive chime at higher volume levels. 

The Dirty channel’s gain control has a very wide range, allowing fine control of moderately driven sounds, with plenty of Dark Terror-approved filth at the top of its travel, making it ideal for everything from classic Brit rock and blues to modern metal.

Best guitar amps: Victory VC35 The Copper

13. Victory VC35 The Copper

One of the best guitar amps for British valve tone

Price: $1,399/£1,129/€1,189 | Type: Lunchbox valve head | Output: 35W switchable to 17W | Valves: 2x 12AX7, 1x EF184, 4x EL84 | Number of channels: 1 | Speaker: N/A | Weight: 8.5kg | Key Features: Footswitchable

Versatile tones, with a sweet spot for AC-esque chime
Footswitchable effects loop
Super-tough build
You have the extra cash for the Deluxe

You could go through the Victory lineup and find any number of contenders for a list such as this, but there is a timeless British quality to the Copper’s voicings that takes the cake.

The Copper deploys a NOS EF184 small-format pentode in the preamp that’s not dissimilar to the EF86 in early Vox amplifiers, and that harmonically rich treble and sumptuous dynamic response is there in spades.

But the Copper is more than just a throwback to Vox. If the ‘60s pop-jangle is its bread and butter, dialling up the gain finds something very musical that’s ideal for classic rock. Set clean and sweetened by the reverb, it has a quasi-American boutique vibe, and a response that feels just right for blues. 

The Copper takes pedals well, it’s portable, and when you compare it to the overheated US market for deluxe amplification, it offers excellent value. The pricier Deluxe version has valve-driven spring reverb and tremolo.

Best guitar amps: Marshall 2525C Silver Jubilee Combo

14. Marshall 2525C Silver Jubilee Combo

Slash’s Appetite tones in a compact combo

Price: $1,499/£759/€866 | Type: Valve combo | Output: 20W switchable to 5W | Valves: 3x ECC83, 2 x EL34 | Number of channels: 2 | Speaker: 12" Celestion G12M Greenback | Weight: 19kg | Key Features: DI Output, Effects Loop, Footswitch

Classic 1987 Marshall mojo
Ideal for Slash tones
Underrated cleans
Switchable power
No reverb

For many years, the Marshall Silver Jubilee was the amp that got away. Produced in limited numbers in 1987 to celebrate 50 years of Marshall, the Silver Jubilee is effectively a JCM800 that has been factory-modded to run a little hotter, and it was something of a minor tragedy that it never entered the always-in-production category its performance deserved. 

This is the Appetite For Destruction tone, the Slash amplifier, and it’s one of the most rocking amplifiers Marshall has ever assembled. The 2555X head offers it in its original 100w/50w format but the 2525C feels a little more manageable for today’s player. It’s still brutally loud in its full 20W mode, but switchable to 5W, it puts that iconic crunch within reach of the world’s domesticated rock animals.

The gain structure on the Jubilee is something to behold but the Frusciante-esque cleans are not to be sniffed at either. It sounds good with pedals and will definitely stand up to most drummers. At 750-odd bucks, it represents excellent value. It’s a serious rock and metal metal amp.

Best guitar amps: Mesa/Boogie Mark Five: 25

(Image credit: Mesa/Boogie)

15. Mesa/Boogie Mark Five: 25

A feature-loaded low-wattage head with built-in speaker emulation

Launch price: $1,599/£1,699/€1,899 | Type: Tube head | Output: 25W, switchable down to 10W | Number of channels: 2 channels with 6 modes | Tubes: 2x EL84, 6x 12AX7 | Weight: 7.5kg

One of the best small amps on the market
12 possible sounds
Built-in CabClone speaker emulation
It's not cheap!

Based on Mesa's flagship Mark V, the Mark Five: 25 head is small, perfectly formed and typical of Mesa's superlative design and attention to detail. Two independent channels, each with three very different voice presets, combine with Mesa's iconic five-band graphic EQ for a choice of 12 sounds. You can footswitch between the channels, with the graphic on or off for quasi four-channel operation and preset 25 or 10 watts per channel. 

One of the best features lives on the back panel: a CabClone speaker-emulated direct output, with a speaker defeat for silent recording or practice, using the built-in headphone socket. Despite the Mark Five: 25's long feature list, it's very easy to use and its tones are sensational. 

The rhythm channel covers the shimmering clean tones of the modern Boogie and the fatter 'blackface'-inspired midrange of the fabled Mark I, while the Mark V crunch voice is so deep and three-dimensional you could record an entire album with it. The lead channel is equally inspiring, with a perfect rendition of the Mark IIC's overdrive tone (arguably the most coveted Boogie sound), along with more modern distortion effects that sound unbelievably good when tweaked with the graphic.

Best guitar amps: Supro 169RT Black Magick Reverb

16. Supro 169RT Black Magick Reverb

A vintage-vibe combo with hex appeal

Price: $1,599/£1,529/€1,699 | Type: Valve combo | Output: 25W at 4ohms | Valves: 8x 12AX7EH preamp valves, 4x 6973 power amp valves | Number of channels: 2 | Speaker: 12" Supro BD12 | Weight: 17.9kg | Key Features: Valve-driven tremolo, valve-driven 6-spring reverb, master volume, linked channels

It’s a very cool, portable build
Incredible classic rock and blues tones
Lush reverb and tremolo
Very giggable volume
It’s kind of pricey

Lenny Kravitz was involved in the design of the 169RT Black Magick Reverb, and at his behest there is treble, there is reverb, and there is master volume. But, still, and Lenny would forgive us, the guitarist we think of when we think of the Black Magick is Jimmy Page, with the original Black Magick a replica of his old Supro Coronado.

Those Led Zeppelin tones wouldn’t just fall out of the box; you had to be generous with the volume, but with a master volume control and treble and bass replacing a master tone control, the 169RT Black Magick Reverb offers you a safer passage to those houses of the holy. Linking the channels opens up a new frontier in gain for this amp.

The tremolo has been improved, offering up to twice the rate of the original amps, while the valve-driven six-spring reverb allows for some subtle depth and space or a weekend’s surfing depending on how you set it.

Some Mesa/Boogie amps are set up for the inveterate seekers, players who crave options and lots of them, so the California Tweed feels like a change of pace. It is a simple, single-channel affair, with high and low-gain inputs on a simple front panel with controls for gain, presence, reverb and master volume and a 3-band EQ, and it offers instant access to the finest Tweed tones you can buy, all sauced by the sweetest valve-driven spring reverb.

A five-way rotary dial lets you switch up the California Tweed’s output, offering five different power outputs from a full 40 watts, where the headroom is gin clear, right down to 2 watts, where it is a little more squashed, ideal for the home, and full of Billy Gibbons’ Texas crunch when you dime the gain.

The California Tweed is breathtaking, a throwback to a golden era in guitar amplification, but very much built for today. It’d make a fine pedal platform, with a series effects loop and a Jensen Blackbird Alnico that can handle a lot of volume. Exceptional all round.
