The Roto Choir celebrates the swirling glory of a vintage rotating speaker cabinet.With its
specifically formulated SansAmp™ technology, the Roto Choir takes this concept to the next
level. It delivers the entire signal chain--from the original tube power amp to the low-frequency
speaker and high-frequency horn to the microphone used to capture it.This studio-quiet,roadworthy pedal can be used with guitar as well as keyboards,synths and vocals --and to record direct.

The Roto Choir offers an abundance of easy-to-use, intuitive controls in an incredibly compact,
battery operable pedal. It features a Fast/Slow foot-switch which allows you to ramp up,slow
down, or even stop the rotating speaker.There’s a dedicated Top Speed control to custom set
the rotor speed and a Position control to adjust the virtual mic closer to or further from the
horns. A Biamped switch allows you to change from single speaker mode to Biamped mode,
and there’s a Speaker Sim switch for direct recording.

The Drive, High, Low and Level controls are 100% analog for warm, organic sounds. Stereo output, buffered bypass, and a silent-switching, custom foot- switch actuator completes the package.
You can get lost for days exploring and discovering all the celestial sounds lurking within the
Roto Choir.
