Many years later, in the ‘80s, I was back into playing and recording and looked in the want ads for a Fender tube amp. That amp turned out to be an early-production 1960 Pro-Amp.
I started to investigate the world of pre-CBS Fender amplifiers.
I eventually traded it in for a used blackface Showman with a 15” JBL.
That amp worked pretty well with my Rick 12-string.
