Guild Quantum Amplifier
Delivers that hard-driving, up-front, "Motown"-type sound - without going through the engineers control board
|The Guild Quantum X bass amplifier|
Initially there was just one version of the Quantum amplifier, with two more models being added to the range in 1969. Each used the same amplifier (head), but with differing quality speaker cones within the cabinet. All were suitable for the bass guitar and organ, with the Quantum X also suitable for electric guitar.
This amplifier was heavily promoted at the time; see the vintage Guild Quantum amp advertisements.
