Maestro PS-1A Phase Shifter Vocoder This is a rare find

This is a rare find - a boxed and near mint Ace Tone FR-3 dating from c1967

CONDITION: The condition is very good overall - the usual scuffs and scratches to the metal case

but was well-worth the effort and grey hairs because the sound is truly superb

Sustain Fuzz: Special circuits detect the beginning and end of each note and apply upper harmonics

That's why we've had this modified to accept a guitar level input and to give a wet-dry mixed output - the balance can be adjusted via the internal trimpot
