This is the rare Roland VX-120, a stereo six-channel mixer with a built-in bucket brigade delay. The delay will self-oscillate if you push it, and it sounds great. You can also run external effects through it and choose the internal BBD or the external effect on each channel, in addition to EQ and panning. I don’t know if the built-in amplifier works, but the stereo outputs do. The aesthetic condition is pretty great and it has that classic Roland style with the same knobs as the Roland RE-201 Space Echo. The RE-201 sits on top perfectly. I think this sat in storage for a long time, as a couple of the channels need to be used extensively to get rid of the scratchiness. Or just spray them with some De-Oxit. It runs on 117v North America. The demo video in the photos section of this listing is of the actual unit for sale.
