This 1967 Bassman wears the "drip-edge" aesthetics, indicating was produced right after the blackface era, but prior to the circuit changes done to the later silverface amps. These are often considered to be a good value buy, as they have the same circuit as it's Blackface counterpart, but at a reduced cost. This one has had seen it's share of gigging, and has pretty heavy wear - though it has held up well. It's undergone some changes inside as well, aside from the changed output transformer all of the original components have been swapped out for modern equivalents. The resistors are metal film, which makes for a much quieter amp compared to the original carbon comps. Please see pictures for further details. Despite the changes this amp still sounds excellent, and is a great value buy for the money!
