I was reading the valveking thread, and I stumbled upon this one guy (311zoso I think) that claimed to turn his fender FM 212 combo from mono to stereo.

I've got a FM 412 w/ V30's, and I would love to make it stereo, but couldnt find a mono to stereo mod anywhere on google or the UG forums.

if someone could shed some light on this mysterious "mono to stereo" mod, I'd be forever greatful
