AC 30 Super Reverb Twin Top Boost Head+Box JMI Product 1965

1965 VOX AC30 Super Twin Reverb Top Boost (AC-30/6 S/T) electric guitar amplifier. Perhaps the most desirable 1960’s amplifier ever made, the AC30 has been showcased on some of the most famous recordings of all time, and has become synonymous with the tone of classic British rock. This particular Super Twin Reverb AC30/6 is in very excellent 100% all originalcondition, and sounds absolutely spectacular. Perhaps the rarest mid-’60s AC30 model, this is the definitely the most deluxe version, with a separate cabinet, an amp head featuring both factory Top Boost and Reverb. Both VOX enthusiasts and tone fanatics will rejoice, as this is an incredible sounding exotic example.

The original version of the AC-30 Super Twin head used a standard AC-30/6 amplifier chassis installed into a rectangular head cabinet.Vox felt that separating the head from the speaker cabinet would improve dependability over the combo version of the amp by isolating the chassis from the direct vibrations emanating from the speakers.
The AC-30 "Super Twin" Speaker Cabinet. The Super Twin speaker cabinet was an adaptation of the original AC-30 combo amp cabinet, less control panel cutout. The number of handles was reduced from three on the combo amp to one on the speaker cabinet. Super Twin speaker cabinets normally had closed backs, or were "pressurized," using Vox marketing speak. Closed backed cabinets enhance low end response, thus improving the performance of the AC-30 for bass guitar. However, not all AC-30 Super Twin speaker cabinets had closed backs. Some shared the same split open back configuration as the combo amp.Two 8 ohm Celestion/Vox 12" alnico speakers, wired in series to 16 ohms, powered the cabinet.
The Redesigned 1965 - 67 AC-30 "Super Twin" Amp Vox ramped up the appeal of the AC-30 Super Twin amp series in 1965 by adding an optional chrome plated tubular steel swivel trolley, installing Top Boost circuitry in the main control panel, incorporating a reverb circuit and converting the head cabinet to a trapezoidal, or "slant sided" shape. This new amp was known as the AC-30 "Super Reverb Twin."
