This amp and pedal have been tested and everything appears to be in good working order. There is some crackling noise when adjusting certain knobs and switches but then goes back to being quiet and sounding great. So, I would recommend that this amp get a good thorough cleaning and adjustment from a qualified tech. Issues that I can visibly see are 2 corner protectors missing, no ID/serial number plate, no "SOLID STATE" emblem on the front, the front bottom particle board is cracked, and the front grill material has been stapled-on. The plug has been changed to a 3-prong type and there are dual 1/4" output jacks on the back. Please call me to discuss if you need other info.
