The Roland Audio Destruction Patch Box sold by Circuitbenders.uk is probably the easiest, most convenient and most elegant circuit bend of all time leaving the original instrument untouched. No soldering, no modifications, you don't even have to open the enclosure of your classic Roland R-8, Roland R-8m, Roland U-110, Roland U-220 or Roland MV-30 - just put the fake ROM card into an expansion slot and go to town on the external patch box. Instant circuit bending goodness, ideal for hardcore techno or industrial.
