Description
A vintage 1964 JMI Vox AC30/6 Normal tube combo amp in player-grade condition. This amp has received an after-market top boost mod which, according to the previous owner, was performed by amp tech extraordinare, Cesar Diaz in 1987. This story is bourne out by the multiple Cesar Diaz "tags" on the inside of the amp. In addition to the Top Boost mod, Mr. Diaz also installed a cooling fan under the lower chassis to dissipate heat away from the vulnerable and extremely valuable original Albion transformers.
The amp has just been serviced with brand new F&T power supply filter capacitors and a handful of other components where required. Additionally the power tube sockets, which could no longer hold onto their top-heavy EL84s, were replaced with new Belton sockets to ensure future reliability.
Some info about the dating of the amp...the top back panel is covered in smooth tolex, while the rest of the cabinet is covered in rough tolex. Smooth tolex cabs with round-corner back panels were only produced in mid 1963, shortly before the transition to rough tolex cabinets. The back panel serial number indicates late '63 as well. Most of the circuit board components with codes date to 1962, and the speakers date to early 1964. It is our policy to date an amp based on the lastest dated original component. However, it is possible that the chassis and back panel came from a 1963 AC30, and the rest of the cabinet and speakers are from a different amp manufactured in early 1964
Soundwise, the Top Boost-modded Brilliant channel delivers iconic mid-scooped, jangly Beatles tones while the Normal and Vib feature the big midrange and smooth breakup of earlier Vox amps. The overdrive tone is rich and full, retaining the classic Vox "chime" without sounding overly bright. It also features the unique Vibravox dual-mode Vibrato/Tremolo circuit. The perfect amp for any serious player or recording studio. This amp has been cleaned and serviced. It is fully functional and sounds incredible.
