This is what it looks like – the brand-new Vox AC4 C1 Blue. I can already hear many of you thinking “What? Another AC4? Is it any different to the white AC4 TV?”
Granted, it is somewhat bewildering that Vox have several similarly named products in their range, so let me run you through the differences quickly:
At the moment of writing there are five different Vox AC4 valve amplifiers available. The Vox AC4 TV – which is available in three different guises – is the most affordable alternative, and aimed at the same market segment as ultra-compact modelling combos, such as the Roland Micro Cube.
At the other end of the price spectrum you can find the Vox AC4 HW, which is a very stylish hand-wired (HW) combo for the vintage fanatic. Just like the Sixties original, the AC4 HW is also equipped with a 12” Celestion speaker.
The new AC4 C1 Blue conveniently slots into the range between the two other AC4s. Vox’ C–series comprises new versions of the company’s most famous models, updated with nifty modern features.

The Vox AC4 Blue (current street price in Finland 349 €) is a very beautiful combo amp, sporting the blue vinyl finish found on one special run from the Sixties, complete with the salt-and-pepper grille cloth.
Two 12AX7 valves are making up the preamplifier section, while the power amp is utilizing a single EL84. Output power is rated at four Watts (RMS) using a 16 Ohms speaker impedance.
The combo’s almost completely closed from the back. The back panel sports only two connectors – one for the power lead and another for connection of an external speaker. Ventilation is provided by a small opening right at the bottom of the combo’s back, as well as the customary small grille next to the carrying handle.
As is the case in quite a number of modern small valve combos, access to the valves is rather restricted in the AC4 C1 Blue. To change preamp valves you have to completely take off the whole back wall to get to the valves, which sit directly on the PCB-board. The owner’s manual recommend leaving valve exchanges to qualified service personnel to avoid the risk of an electric shock.
The Vox AC4 Blue comes equipped with the same special design already used successfully in the AC4 TV – a 10-inch Celestion VX10.
The front panel comprises controls for gain, bass, treble and master volume.

Vox has aimed to deliver genuine Top Boost –tone in a small package, and the AC4 C1 Blue really dishes out the goods. This little combo gives you all the legendary AC30 sounds, but at volume levels that fit your living room or home studio to a tee.
The AC4 C1 BL’s clean tones have plenty of jangle, coupled with Vox’ typical dose of grit and attitude. If your’re using powerful humbuckers, you’d better turn down your guitar’s volume a bit, unless you want to drive the combo into light Blues-overdrive.
For my taste the little Vox could do with a little bit less bite in the top end, but I got the trebles reigned in easily with the Treble-knob.
Upping the gain gets you into overdriven territory fairly quickly – from creamy Blues all the way to early Heavy Metal via Seventies Classic Rock. For out-and-out Nu-Metal the Vox AC4 Blue isn’t really the right amp, it just wasn’t designed to dish out that much grunt. For Brian May –type fat lead tones I’d recommend using a distortion pedal in front of the combo.
With its four Watts the AC4 C1 Blue has just enough power to annoy your neighbours – and for small gigs you could stick a microphone in front of it.
Here are a few soundbites (all clips start from the neck pickup):
