Condition Note
This amp is in excellent “player grade” condition. The electronics have been maintained with high-quality JJ tubes, and the 3-prong grounded plug ensures modern safety standards. It shows typical cosmetic wear for an amp of its age, the tolex is dinged and peeling from corners and edges, the grill is dirty, but it is structurally sound and sounds absolutely massive.
