In this video we will thoroughly explore a 1962 (or 1963) Brownface Fender 6G6A Bassman amplifier, with emphasis on creation of an adjustable bias pot and in-depth discussion of both NFB circuits and the Fender Presence Control. An audio demo is presented at the end of the repair segment. In addition, we will be visited by some kitties, a 1932 Ford Roadster, and a very special guitar.
