Important Information

+ Power supply included.

The Roland Revo 30 (effectively the amplifier head from the Revo Sound System) is a vintage Japanese-made analog rotary speaker and Leslie simulator produced by Roland around 1975 to 1978. Rather than using a physical spinning horn or rotor, it uses an internal Bucket Brigade Device (BBD) IC chip circut (acting as a phase-shift/chorus/vibrato engine, often compared to the original Uni-Vibe) to pan and modulate sound across stereo or quadraphonic outputs.
