    I found this exact same amp in my fathers home after his death. It works amazingly well. I would grade as in very good condition. Could you tell me who might be able to give me a ballpark figure on the value.

      J. Bonamassa is also a huge Fender Twin guy, and is approachable sort of. Or at least as approachable, as the pursuit of a vintage Fender amp makes him…ha!
