Fifties and sixties guitar amplifiers in the spirit of the Valco and Danelectro ODMs of that era.

These amps were built using circuits that closely ressembled the premium Fenders of the fifties. While surplus loctal tubes were often used (potentially to save costs), quality Alnico speakers and transformers (same manufacturer that Valco sourced) were installed in all amps.

Pictured at left are two Sierras, models F7B and E5C, and a Royal E5C. The cabinets date to 1958 and 1959 for the Sierras and the Royal is a 1957.
