Multivox Guitaramp 1967 preset

Verified · 80/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

This 1967 Multivox guitar amplifier represents the mid-1960s production from the New York-based Multivox organization, which manufactured and imported instruments and amplifiers under several brand names. Multivox amps from this period used American-style tube circuits with warm, natural compression and were popular student and semi-professional instruments. Surviving examples are now collected for their vintage American tone and period character.
