I had the Bass amp that looked like that, was called a B-100? had same knobs and grill cloth but a 15" combo. It was solid state and I believe from 197?. I bought it in 1980 and it was well used. I sold it in 1996 to a guitar player who chose it over a 100 watt Laney I had for sale too. Said it was louder and cleaner. Did you ever see one of those Yamaha apms that looked like a piece of cheeze, They had plastic speakers shaped like an ear. They were terrible. I bet That amp you have there would compair to a Roland Jazz Chorus for punchy clean.
