Yeah, yeah, I know this 1939 Gibson guitar amp didn't "invent" electricity...but it was darn close. In this video, we'll service it with a new speaker, some fresh output tubes, look at the schematic, and try to fix a few small bugs before demonstrating it with a Strat, a D'Angelico DC Premier, and a Gibson ES-335.
