Dumble modded Brown Deluxe amp from the Santa Cruz era. It has a beautiful raw and crisp voice. This 1962 Fender amplifier was worked on in the 70s by Howard Dumble, as he called himself at that time. The speaker was signed "Howard" and a partial date, see the pictures. The circuitry was updated with parts specific to the Dumble Santa Cruz era, and the tone reflects that. It is not the smooth Ford tone, it is raw and expressive, and compresses into a gorgeous lead tone when cranked.
Transformers are original, cabinet was retolexed by Larry Rodgers.
