I bought this amp several years ago and have used it lightly since then. The pot on the second channel volume will likely need to be replaced, as volume cuts out when the knob is adjusted. I have experienced occasional high-frequency feedback with the reverb which is stopped by switching the reverb on and off. Original foot switch is included. Tubes are Groove Tubes GT 12AX7/GTAT7 except for V6 which is a JJ Electronic AT7. I can throw in 1/4 inch cables if interested.
