Good working order. Very similar to the Korg units of the day which were made famous by The Edge of U2. Works as it should. This rare piece is a rackmount digital delay with modulation (so chorus, flange, slapback, etc.), and the ability to do one-shot sampling right from the front panel. No presets - it's immediate. It's from 1988, and it has that 12-bit early digital grunge going on. Manual Here: https://peavey.com/manuals/80300544.pdf
