I had that same early Peavey Bass amp from about 1976. It was the first amp I owned that could handle the all the balls my '67 EB-2 put out at high volume. Prior to that I had a Mosrite Award amp, a piece of crap. It would break down constantly. I carried a Fender Bassman, (blackface), along as a spare, using just the speaker of the Mosrite.
