BOSS RT-2 Rotary Ensemble Pedal

BOSS RT-2 Rotary Ensemble Pedal

The BOSS RT-2 Rotary Ensemble brings the unmistakable movement, depth, and swirling character of a classic rotary speaker system into a compact pedalboard format. From subtle three-dimensional motion to intense, psychedelic modulation, the RT-2 delivers an exceptionally expressive rotary experience for guitar, bass, keyboards, synthesizers, and more.

Three distinct MODE settings provide different rotary voices, while dedicated SLOW and FAST controls let you shape the rotor speeds. The RISE/FALL TIME switch controls how quickly the effect transitions between speeds, creating everything from smooth acceleration to dramatic performance changes.

The RT-2 goes even further with a DRIVE control for vintage tube-style saturation and a selectable BALANCE function for shaping the relationship between the virtual treble and bass rotors. Stereo inputs and outputs, external footswitch support, and expression-pedal control make the RT-2 exceptionally flexible for advanced rigs.

Northeast Music Center

At Northeast Music Center, we appreciate effects that don't simply add another sound, but actually change the way an instrument moves and responds within a mix. The RT-2 provides rich spatial movement, authentic rotary character, and deep performance control in a format that fits comfortably on a modern pedalboard.
