I bought this ART Multiverb in working condition, but have only ever plugged it in to see that the lights came on (they do). This vintage effects processor can be mounted in a 19" rack to provide stereo effects in the studio or as part of a guitar rack.
This 20 bit (higher res than CDs) TRUE STEREO processor can provide several effects simultaneously and with lots of control. Reverbs, delays, pitch shift, vibrato, tremolo, thickening, chorus, flange, and incredible, very distinctive phase shifters, plus a LOT MORE.
