The RT‐2 Rotary Ensemble authentically captures the mesmerizing modulation effects of vintage rotary speakers in a space‐saving BOSS compact pedal. Initially developed for organs in the 1940s, rotary speakers used motor‐controlled components that physically spun at variable speeds, producing a rich, dimensional sound that guitarists and other musicians have used to infuse classic tracks with deep, swirling character.

At the heart of the RT‐2 is a faithful recreation of this iconic sound, featuring a spinning high‐frequency horn (treble rotor) and a rotating drum for low frequencies (bass rotor). Transitioning between fast and slow rotor speeds produces expressive tonal shifts, now enhanced with modern flexibility thanks to dual‐speed control, a Rise/Fall Time switch for adjusting transitions, and a colorful virtual rotor display that shows the current rotation state in real time.

The Drive knob introduces vintage‐style tube saturation, from mild warmth to gritty breakup. A rear‐panel Drive/Balance switch allows this same knob to adjust the volume balance between treble and bass rotors. Your most recent settings for drive and balance are automatically saved and recalled on power‐up. The RT‐2 also supports advanced control with expression pedals or external footswitches, including a rotor “brake” effect that stops the virtual rotors mid‐motion for unique textures.
