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
1964 was the final year of the Brown grill cloth on the AC4. Compare this amp with a 1965 example
, with new black lattice cloth and smaller Vox logo.
From behind the speaker is clearly visible. Note there is no tremolo controlling footswitch in this example.
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).
This amp is fitted with a larger Vox logo (approx 100mm x 34mm)
The fuse is removable for either 230v (UK) or 110v (US) operation, greatly increasing the export possibilities for this unit.
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.
This is perhaps the classic Vox grill cloth: brown with stitching in green, red and yellow - this was replaced by almost identical black cloth - actually red, green and white diamonds on a black background in 1965.
The plastic identification backplate is quite worn in this example. It would read: "Vox Amplifier - manufactured in England by Jennings Musical Industries Ltd". The serial number and model designation are actually stamped into the plate; far more durable than the other lettering. 82mm x 101mm
