Boss RT-20 Rotary Ensemble Pedal

Countless guitar heroes have embraced the rotary-speaker sound on stage and in the studio.

With this in mind, BOSS proudly announced the newest member of its Twin-Pedal family: the RT-20 Rotary Sound Processor.

Employing COSM modeling technology, the RT-20 authentically reproduces classic rotary speaker sounds, and beyond.

It offers adjustable Rise Time, Horn and Bass speed, and Overdrive -- and not just for classic twirl -- the RT-20 can be used to create unique overdrive and pulsating effects as well.

This pedal also offers a stunning graphical view of the virtual rotors on its built-in display.
