The title and topic description say it all; I have a K250-4 that is a great amp except the entire reverb assembly is missing. I even swapped in another 150-ohm tank and verified that all the electronic circuitry is working fine; why on earth would you do that to an innocent amp? Help would be greatly appreciated. I'd also be interested in a four-button light-up footswitch and wah pedal for said amp...sadly also gone.
