Back in the fifties, a low-powered amp was all you could have. Then as bigger amps were invented, if you could afford it, you'd trade up.
But a powerful amp isn't always the answer: they're too loud for home playing and recording, and with advances in PA and monitoring, a lot of people don't need the sheer stage volume. Cue the recent trend of little amps, first expensive and esoteric, then cheap and Far Eastern.
The AC4 name first appeared back in 1961, by which time the cream cloth vinyl had been superseded, as had the 1958-60 TV-style cabinet design. So the current AC4 is more an exercise in general vintage aesthetics rather than a specific reissue.
We have a single 12AX7 in the preamp and a lone EL84 class-A power section. Top whack is four watts, while a three-way power attenuator enables you to pare that down to one watt and – wait for it – 0.25 watts!
You get volume, tone and a 16-ohm speaker output for a 4 x 12 extension cabinet should you wish, or indeed the matching Vox V112TV 1 x 12.
Amp buffs might sniff at the AC4TV's particleboard cabinet (ply is generally considered better) but it's such a dinky little thing, it doesn't need ply for longevity and it's questionable how much it would 'improve' the tone of such a small, closed-back box. Likewise, corner protectors aren't required, and the retro cream plastic handle could take double the weight.
The AC4TV combo comes as standard with a 10-inch custom-designed Celestion VX10 30-watt ferrite-magnet speaker that's rear-mounted to a particleboard baffle.
Plug in on the highest power setting, crank it up, and the neighbours will already be banging the walls down. It's too loud for domestic use, but perfect for rehearsals and the studio.
There's a slight element of boxiness, as you'd expect from a small cabinet. Its strong mid-range is so much more a part of 'real' rock 'n' roll guitar sounds than many modern bass- and treble-heavy tones, which sound good in isolation yet struggle in a recorded or live band mix. The closed-back, ported baffle design helps keep the low-end tight and focused.
With a vintage-style Strat and the four-watt setting, things stay clean to around 10 o'clock on the volume control, beyond which you veer into a light overdrive that doesn't suffer from raspy treble. At around two o'clock there's an audible hike in gain and we're into classic rock drive textures that will clean up again if you knock the guitar's volume back.
Swap the Strat for a Les Paul Standard and the drive texture thickens and smoothes as the mahogany and humbuckers keep a firmer hand over the whole shebang – a thick, satisfying, Bonamassa/Moore-style lead tone when cranked.
Switching down to one watt cuts headroom dramatically, enabling you to achieve drive at lower levels. Down again to 0.25 watts takes that a step further, where you can max the volume and tone for a lovely compressed distortion that just seems to knit everything you're playing together – like a 50-watt Marshall 'Plexi' or an AC30 does when they're blowing your ears out. It's a brilliantly conceived and superbly executed feature.
There's enough variation in the tone control to span dark and muddy through to present and cutting, but definition can be an issue with neck pickups, particularly if the amp is sited in the corner of a room.
So cute it hurts and it sounds great for all manner of rock 'n' roll and classic rock tones, it's better than an Epi Valve Junior, but not as full-featured as the Blackstar HT-5, which makes the £219 tag seem about right, albeit still ludicrously cheap for an all-valve amp.45 Stars
