4w guitar amplifier made by Jennings (JMI) in Dartford, UK. Single 8" Goodmans speaker. Black tolex, brown diamond lattice cloth. Dimensions 16" x 16 1/2" x 7 1/2". Weight: 7.6 kg
The Vox AC4 had a February 1964 list price of £23 2s 0d - compared to £115 10s 0d for an AC30. This was comparable in price to Vox's entry level solid body guitars. In the same price list, a Vox Stroller was listed at £19 19s 0d, whilst Clubmanwas £22 1s 0d.
The controls consist two inputs, volume, and tone (this is also the on/off switch), and a speed control for the (missing) foot-operated tremolo. The pointers are unbranded black chicken-head knobs, though they may be white in other examples (compare with a 1965 Vox AC4).
The 8" speaker is branded Goodmans Industries Ltd, Wembley, Middlesex - and like the amp itself - made in England.
Vents are plain brass. By 1965 these would be replaced with plastic Vox branded pieces - compare with the 1965 Vox AC4 featured on this site.
Here are a selection of demo clips of various vintage guitars using this amplifier. This truly is a sweet sounding amp!
This is a really cool British-built vintage guitar from the early 60s. Nice sounding, with plenty of mellow with the neck pickup selected and the tone rolled down, but maybe not as much bite as you'd expect from the bridge pickup alone. (Perhaps the springs should be removed to raise the pickup further). The tremolo is pretty useable, and doesn't detune the guitar significantly with a little use - i've not really tried any dive bombs mind you! The AC4 is a cool amp, with a beautiful basic sound; it isn't really loud enough to disturb anyone else, but this does mean it doesn't get especially gainy either. I generally wish it would give a little more... Strung with Gibson bright wires (10-46).
