10 of the best-value used amp heads

(Image credit: Future)

Introduction

In my most recent article I waxed lyrical about some of the world's most desirable channel-switching heads - amps like the Suhr PT100, Bogner Ecstasy 101b and Friedman BE-100. These no-holds-barred boutique amps have graced prestigious stages all over the world and are still relatively reasonably priced in the grand scheme of things.

For the price of a 10-year-old hatchback, you can stand in front of the same amp as many of the greats - and experience the work of some of the industry's finest designers and engineers first hand.

Rock 'n' roll (opens in new tab), though, started out simply. Many of the records we all love were made using mainstream, off-the-shelf equipment.

Sure, the best boutique gear has the knack of presenting the most desirable sounds in a box that looks, sounds and feels great; but the sounds themselves were fundamentally cooked up using very simple ingredients. For all the unmitigated joy it brings us, the boutique revolution will not change that.

Surely, in a world where an original Marshall 2555 Silver Jubilee or Mesa/Boogie Mark IIC+ can change hands for ludicrously inflated prices (and I take nothing away from these magnificent amps - it comes down to simple supply and demand), there must be some similarly brilliant amps that for one reason or another have flown under the radar, or have not yet succumbed to the vagaries of fashion?

Marshall JCM900 2100/2500

Not to be confused with the relatively humdrum 4100/4500 Dual Reverb Series (which itself represents a ridiculous bargain in the Marshall world), the 2100/2500 amps were an indirect continuation of the line of MKII Master Volume and subsequent JCM800 single-channel amps, and in many ways are just as special.

It's a relatively little-known fact that the single channel JCM800s were sometimes known as MKIIs and were really just a glitzy '80s re-packaging of the late '70s MKII Master Volume heads. The MKIII amps essentially continued that single-channel tradition under the JCM900 moniker, adding an extra diode gain stage as had already proven successful in the Silver Jubilee and JCM800 split-channel amps.

These amps provided a fantastic medium-high gain sound that fell somewhere between that of the chewy Jubilees and the brash 2205/2210 split channels, all delivered with the authority of a JCM800-derived power stage and the convenience of a modern effects loop.

After just two years, Marshall moved away from the diode clipping stage and morphed the MKIII into the cosmetically similar SL-X amps (occasionally known as the MKIVs), replacing the diode stage with an extra preamp valve stage and retaining the 2100 (100W) and 2500 (50W) model numbering system.

These amps are similarly brilliant, and with the two gain controls carefully blended around halfway they can do a disgustingly good impersonation of a JCM800 2203/2204. They still have the benefit of relatively modern levels of available gain, they retain the great effects loop, and they add the inestimably useful dual master volume feature.

The MKIII and SL-X amps do tend to inspire a lot of conflict among Marshall enthusiasts (the age-old diode vs tube debate rears its ugly head here), but the reality is they are both among the best-sounding amps Marshall have made, and they are normally available for less than half the price of a good JCM800.

With the later (and also great-sounding) 5881-loaded amps being made until the late '90s, with a little patience, there is 2100/2500 for every taste.

EVH 5150 III 50W

The 100W version of this stadium-ready amplifier appeared in my last round-up; and with used prices as they are, it could easily have appeared here, too. But the award for value goes to its little brother, which repackages the same three channels into a head of half the size, and commands a used price in line with that of a decent mountain bike.

Here is a compact and relatively light amp that delivers one of the most widely recorded modern metal sounds, one of the greatest rock rhythm sounds of all time, and a useful clean. It's a neat, seamlessly switchable, MIDI-controllable package with a world-class effects loop; and it's small enough to sit on the passenger seat of your car.

The one catch with the 50W head is that the controls are shared between the first two channels, so its pure clean sound is rather compromised if the blue channel is to be used to its fullest. Better to treat this as a 'gritty clean' channel or add an effects processor to manipulate final volume settings per channel. With an amp this good-sounding and MIDI control this seamless and well-integrated, it's well worth the effort.

Peavey Classic 50

The Peavey Classic series has been quietly exceeding expectations for close to four decades now. Its old-fashioned cosmetics were something of a revelation in the Peavey line when released - but don't let the looks fool you.

This is a full-powered rock monster, and its chewy, gritty yet thick distortion sound provides a genuinely classy alternative in the traditional Marshall vein. It's touch sensitive, dynamically responsive and remains fat and woody enough for lead work. 

The useful clean channel, excellent effects loop and Peavey's renowned tour-ready build quality provide further reasons to buy one - as if the ludicrously low price weren't incentive enough.

Biffy Clyro's Simon Neil recorded and toured with the closely related Delta Blues for years, and the wonderfully sweet yet robust Classic 30 combo provides another practical gigging alternative. Buy one now, before everybody finds out.

Peavey 5150/6505

The second Peavey to make the cut; it's hard to believe this behemoth has been continuously in production (and unchanged apart from the 6505 rebrand) for over a quarter of a century.

Peavey was already on a roll with the Classic Series, and the addition of one Eddie Van Halen to their artist roster made them the name on everybody's lips for most of the early-to-mid-'90s. 

It would be tempting - and not horribly inaccurate - to describe this amp as 'the sound of modern metal'. It would also be all too easy to sell it to you as a "poor man's Soldano SLO", which in some ways it is. But to pigeonhole this magnificent amp in either of these ways would be to do it (and the SLO) a monumental disservice.

The key to understanding the Peavey 5150 range is actually very simple: it has no clean channel. None, at all. At a 5150's cleanest settings it is already beginning to break up, and not exactly in the prettiest way. To attempt to excavate a clean sound from this amp requires the patience of a saint and the complete sacrifice of the utterly wonderful crunch mode.

No: this amp needs to be treated as EVH himself would treat it. With the first channel gain set around halfway or higher, it can swerve instantly from a gritty and authoritative Bassman breakup to a modded-Marshall chunk just by virtue of engaging or disengaging the Crunch mode.

This channel alone is so responsive to the guitar's controls that most rock, blues, even indie/pop or hard country gigs could be dispensed with in a heartbeat - as long as a true clean sound was not required. The blistering, genre-defining second channel can then be assigned solely to lead work, or reserved for high-gain material as the need dictates.

The 5150 II or 6505+ provide further control and flexibility; the great effects loop, switching and roadworthy build are long-standing Peavey hallmarks; and the used price is practically laughable for an amp that has graced and still graces so many major stages the world over. 

Marshall 6100 30th Anniversary

Another quietly overachieving Marshall from the early '90s, the 6100 marked Jim Marshall's 30th year in the amplifier business, and was Marshall's first three-channel head.

It also contained a wealth of modern features like MIDI control, pickup compensation, variable wattage, pentode/triode switching and more - and cleverly packaged all of this complexity into an amp that looked and felt like Marshall's flagship. Conveniently, it also had the tone to match.

With each of the three channels being 'plumbed' directly through its own preamp tubes to the shared output stage, this was an incredibly pure and organic-sounding beast considering the complexity built into it, with a complement of tones to rival any Marshall ever made (apparently it made quite an impression on Reinhold Bogner upon its release as well!).

This was the Marshall that should have changed the world - yet, somehow, didn't. It did appear on Rush's Test For Echo, and was a staple of Steve Cradock's (Ocean Colour Scene) as well as being Joe Satriani's live amp as a platform for his modified DS-1 pedals until the early 2000s.

It never quite entered into the public consciousness in the way that the '60s, '70s and '80s Marshalls had, though - perhaps we guitarists like our Marshalls simple and brash? It was essentially replaced by the JCM 2000 Triple Super Lead in the late '90s and was sadly never widely mourned. Consequently, the 6100 is still available for a song, and sits happily alongside a catalogue of revered amps if a library of Marshalls is what you need.

Soldano Hot Rod 50/100

If the SLO is the Ferrari of amps, what does that make the Hot Rod series?

Imagine there was a Ferrari available at the price of a family saloon, with all the great hallmarks of Ferrari design and engineering and made in the same factory in Maranello. Now imagine that the performance it offered came within a gnat's whisker of the high-end Ferraris - and that it was built, painted and finished just as well as they were. Costs could perhaps be kept down by sharing more mechanical parts with Fiat or designing simple, robust alternatives in-house. This car, ladies and gentlemen, would fly off the shelves.

This is precisely what Mike Soldano offers with the Hot Rod series of amps. It distills an excellent version of the flagship SLO's Normal and Overdrive channels into a stripped-down box with fewer switches and modes.

Instead of the custom-designed DeYoung transformers, it uses extremely reputable (and by anyone else's standards rather special) off-the-shelf designs by Mercury Magnetics or O-Netics.

Internally, it cuts a few corners (like having PCB-mounted as opposed to chassis-mounted tube sockets, for example) but still offers industry-standard build quality; in many cases exceeding that of other amps in the price bracket.

It's built in Seattle to the same exacting standards as every Soldano, and it is available second-hand for the price of a rusty 15-year-old Honda Civic. What are you waiting for?

Cornford MK 50

Cornford sadly went out of business in 2013, but for well over a decade it built some of the world's most desirable amps.

In terms of their build quality, they can be most efficiently described as a 'British Soldano', and yet their flagship MK 50H II sold in the UK for an astonishing £1,999 when new.

When the II arrived, the simpler MK 50 model remained in production, offering a simpler and cheaper alternative for those players who wanted all the same top-drawer tones and bomb-bunker build quality - but didn't require a dedicated clean channel.

If you can deal with an amp that offers no product support, has dwindling parts availability - and you are happy to gig with something that will one day be near-irreplaceable - the original MK 50 currently represents possibly the best boutique bargain around.

It contains two genre-defying medium/low and medium/high-gain modes that neatly straddle the boundary between raunchy, woody Marshall and cutting, precise Soldano. It is flawless in build, functionality and execution, and it will not be cheap forever.

Mesa/Boogie Mark IV

Between the now-vintage Mark IIC+ and the all-singing, all-dancing Mark V came the Boogie Marks III and IV. They were actually available concurrently for several years in the '90s, and they are - put simply - two of the very best guitar amps ever made.

The Mark III suffered slightly due to living in the shadow of the all-conquering Mark IIC+, and its then-cutting-edge three-channel switching was decidedly compromised in operation. In reality, it only offered practical switching between two, rather than three, of its best sounds. So the near-perfect Mark IV (with its value now significantly diminished by newer Boogies) is the amp that makes the cut in this line-up.

The Mark IV was the session player's amp of choice during the '90s and early-2000s due to the almost limitless range of sounds it can produce.

It has far too many features, switches and modes of operation to mention here, but at its heart it contains a typically excellent Boogie clean, a range of mid-gain textures that straddle Vox, Marshall, Hiwatt and more, and one of the industry standard high-gain sounds as famously employed by John Petrucci and Lamb Of God among others.

With an inquiring mind and a good ear, this amp will provide a lifetime's worth of world-class tones, and its intelligent design removes nearly all of the switching compromises inherent in the Mark III while retaining pure, organic tone. At current used prices, it stops just short of being 'cheap', but it does represent outstanding value.

Mesa/Boogie Dual Rectifier Solo

It wouldn't be right to talk about the Mesa/Boogie Mark Series without also including its aggressive, outspoken younger brother.

The Rectifier range was primarily descended from Soldano's SLO (itself derived from the Boogie Mark II) and it famously provides the huge, bold and aggressive footprint that, for more than a decade, was almost a prerequisite for nu-metal, rock and grunge, as well as being one of the most recorded amps in modern metal. It remains a recording staple after more than 25 years.

The Recto has always been a fully featured amplifier, but as it's matured, it has grown to encompass a wider range of musical styles. The latest models cover almost every imaginable genre, carrying one of the best clean channels on the market, switchable wattage and rectification style per channel and more.

However, the Recto that currently offers the best compromise between price and performance is the somewhat maligned Solo series, built from 2000-2009. These were the first Rectos to offer three channels, the first with a dedicated clean channel, and they carried a parallel effects loop.

They do tend to suffer from criticism due to being tonally less pure relative to the earlier, simpler models, but they still offer all the same industry-standard tones alongside a high level of flexibility. They have the tone to demolish buildings, the build quality to outlast humanity and their used prices make some mid-priced amps look nothing short of silly.

Marshall JCM2000 DSL

So, on to possibly the most ubiquitous rental/rehearsal studio/house amp in the world. It would be very easy to dismiss the common or garden DSL as 'just another Marshall', or to malign its build quality relative to the older amps. To ignore it, however, would be folly.

It is true that some aspects of the build are less robust than older Marshall designs, and in the earlier models there were a couple of well-documented weaknesses that did tend to show up over long-term use. 

This amp - if you can tolerate another automotive metaphor - is the Ford Mondeo. It is built to a price, it can be found everywhere, and an older model can be bought for small change. However, it is also unassailably the best in its class, sometimes outperforming contenders from a class or two above, and is still being sold after a couple of decades for a raft of very good reasons.

The DSL was nothing short of a revelation upon its release. It splices in the simplest imaginable way a classic Marshall and a modern Marshall into one box. It is laid-out well enough to appeal to both working guitarists and Marshall traditionalists, and can easily deliver boutique-baiting tone.

It provides all the warm, woody, breathing low-gain Super Lead textures in the first channel, and effortlessly mutates from ripping VH to clanging GN'R to smooth sustaining leads on the second. 

The two channels share an EQ section and it isn't an entirely happy marriage, but cheap and simple mods exist for those so inclined - or pedals can be employed to bridge the gap. The DSL (as used in the 2000s by no less than Jeff Beck, Richie Sambora and the late Gary Moore) is a tonal champion: not to be missed.
