The BOSS RT-20 Rotary Ensemble is a killer choice for players who want rich, swirling rotary speaker-style movement without dealing with a full Leslie-style cabinet.

This one is in excellent preowned condition and gives you the classic rotating speaker feel in BOSS’s rugged twin-pedal format. You get slow/fast speed control, rise time, overdrive, horn/bass balance, and the signature visual rotor display, making it easy to dial in everything from subtle movement to deep, pulsing rotary texture.

This is a great fit for guitar, bass, or keys, especially if you play classic rock, blues, worship, ambient, psychedelic, or vintage-inspired tones. It sits in that sweet spot between chorus, tremolo, vibrato, and rotary speaker sounds — but with more dimension and movement than a standard modulation pedal.

Condition: Excellent preowned condition
Price: $249.99
Includes: Pedal only
Power supply: Not included

Why it’s worth grabbing:
The RT-20 is no longer a current-production BOSS pedal, and clean examples are getting harder to find. If you want that rotary-style movement in a reliable stage-ready pedal, this is a strong one to have on the board.
