Amp problem

[scotto]

Late 60's modded Bandmaster suddenly turned into a tone generator that sounds like the synth in Emerson Lake and Palmer's "lucky man." It's a continuous tone that stayed after unplugging the guitar. I let it cool down so I could swap some tubes out but wondered if heat had something to do with it. Turned it back on with same tubes and it's no longer acting like a synth. Anyone experienced this before?

Yes, I have but like yours, the tone went away and never came back.

BTW, I didn't know we had another member in my area, I'm playing in Hillsborough at Pheasants Landing tonight.

Thanks Bob. It was really strange. Hope it never happens again but I hate not knowing what caused it for obvious reasons. I've got plans tonight, but I'll try to catch your band soon since you are local.
