Great amp for someone who doesnt mind some patina and wear, and only cares about great sound! Heavily sun-faded on mostly the left side, right side is largely black still. The volume pot is bent a bit off axis. Sounds great, this amp is just far too large and overkill for my needs. Includes pictured tubes, unknown if they are the original or not. Includes wall power cable, and power passthrough cable, no audio cables. Will be packaged securely with bubblewrap, styrofoam, heavy duty box, etc.
