Used Yamaha GEP50 Guitar Effect Processor - Good Condition

This Yamaha GEP50 rackmount guitar effects processor is in good working order. Some of the input/output jacks were a bit dirty/scratchy; they’ve been treated with DeoxIT and are functioning properly, though they may continue to improve with regular use. The GEP50 is a vintage Yamaha digital multi-effects unit (released in 1988, made in Japan) offering programmable distortion, delay/echo, modulation, reverb, pitch processing, compression, and parametric EQ, with MIDI control and an external insert loop whose on/off status can be stored per patch.
