I was using the unit live with a Marshall Super Lead, and out of nowhere it got really distorted and stopped passing audio in Operate Mode. I took it home, replaced all of the tubes with brand new ones and let them burn in, replaced the internal fuse, and did everything on the no sound checklist using a Fender combo amp, and it is still not passing audio. It was passing audio through the effects loop return. There is sound in bypass mode, so I know the speaker cables are OK.
Is there anything else I should check? I do need this to record in about two weeks, so I’m hoping to have it running by then.
Thank you,
Seth
