Hello everyone! I just came upon an estate sale find, but I'm not exactly sure what it is. It's a Gretsch Guitar amp from apparently the 1950's. The amp does say Gretsch but it has no model number/name or serial number. It's champ-like. It has an 8" speaker and as it has a 6v6, a 5y3gt and a 12ax7 in it's tube layout. Volume knob click to turn the amp. One tone control. Seems like it belongs to the Gretsch Electromatic" family but I can't find anything about this one specifically. Hopefully these photos will help jog someones mind! Any help would be greatly appreciated. Thanks!
