1 Powdog 4 years ago Hey guys. Gonna build a Gretsch reverb unit to compliment my new Model 24. Wondering if anybody would have a schematic for the unit that had an 8" speaker built in, with the boomerang Grillcloth? Also interested in which reverb tank would I use for a model G6144 reverb unit. Same as a Fender? Sure appreciate the help.
