I'm looking for a 50 watt fender reverb head/combo. Here's my idea. Take a '60s or '70s BF Fender bassman head. Remove the circuit board and rewire the thing to be a single channel Fender AB763 reverb amp. I'm thinking that a small reverb tank might fit in the bassman head enclosure. I'd probably remove the existing circuit board altogether and try to make or purchase a blank turret or eyelet board, preferably a "glass" one. I took a look at some of the board kits out there but they are fairly expensive ($250 or more) and the AB763 board is for both channels and includes vibrato which I wouldn't be implementing since the bassman only has 4 preamp tubes. Anyone done anything like this?
