While the circuit design was drawn up in 1963 AA/AB763, the actual release date was March of 1964 as per the final three letter code on the schematic; C FD. These were made for maybe 7-8 months as the AA964, 2×10 Vibrolux Reverb was in the works and released in October of 1964. Mine also has “Normal” and “Vibrato” inputs. The blackface 1×12 Vibrolux doesn’t have much gain on tap and a switch pot to remove the tremolo from the circuit works very well with this and other non reverb models. Mine seems to be on the bright side so I use original Tung Sol 5881’s and a 70’s Celestion black back G12M-55hz in it. I agree with M Karlson; this amp should have evolved into a single 12″ with reverb. It may have been the best amp Fender never built!

A number of years ago, I found a 1966 Blackface Vibrolux Reverb that someone before me had replaced the two 10’s with an EV 12L Pro Line. The amp weighs a tone, is loud as all get up, but sounds fantastic. Cool thing, I only paid $270.00 for it. Although it’s not vintage, it’s great to hear that very set-up you’re mentioning above. It is very versitale and takes pedals well.
