I just sold my Concert Lead without much knowledge of whether or not it was working properly, so I offered to refund his money if he doesn't think it was in proper working order. He told me the reverb isn't working - again, I never used the reverb, so I wouldn't know - he says it just feeds back when you turn the knob up.
I was under the impression that the reverb on a Concert Lead wouldn't work without the footswitch, kinda like the distortion. Am I right? Or is the reverb on this thing screwed up?
Any help is appreciated, if it's messed up I need to give him his money back ASAP.
