My friend is selling his red knob Concert Lead with the original footswitch. It is in extremely good condition, the tolex is clean, hardly any oxidation on the metal parts and the chassis shows very little wear. The only work I'm aware that has ever been done on the amp is a replacement power switch because the original was smashed. He's looking for $500 to recoup his initial investment. Looking to deal in Southern California. Open to trades for cool tube amps.
