Rotary Revolution

Rotary speaker cabinets sound amazing, but their size and weight make them impractical for anyone but the most dedicated vintage enthusiasts. Powered by the latest BOSS advancements, the RT-2 Rotary Ensemble distills this expressive spatial effect into a footprint that’s easy to integrate into every setup. This powerhouse pedal authentically recreates the complex sonic magic of its inspiration, supported by three sound modes, deep tonal shaping, and advanced operation with the onboard pedal switch and external control.

Features

Authentic rotary speaker sounds and behaviors condensed into a space-saving BOSS compact pedal
Three versatile modes include a vintage rotary sound and two modified tones with enhanced spatial effects
Virtual rotor display with lights that indicate treble and bass rotor speeds
Fast/slow rotor speed control
Drive knob to add vintage tube saturation
Rise/Fall Time switch adjusts the transition time between rotor speeds
Drive/Balance switch assigns the Drive knob to control the saturation amount or the volume balance between the treble and bass rotors
Four selectable pedal switch modes for bypassing the effect and controlling the rotor speed in various ways while performing
Support for advanced control with external footswitches or an expression pedal (speed, brake, and other functions)
Mono/stereo input and output
Two stereo output modes: standard stereo (default) or individual wet and dry outputs
BOSS five-year warranty

Rotary Magic

Initially developed for organs in the 1940s, rotary speakers produce mesmerizing modulation effects with motor-controlled components that physically spin within the cabinet at variable speeds. This impressive sound is a vital part of the classic combo organ voice, and guitarists and other musicians have also employed rotary speakers to infuse iconic tracks with their distinctively rich depth and movement.

Authentic Performance

The most revered rotary speaker designs feature a spinning high-frequency horn (treble rotor) and a woofer that feeds into a rotating drum (bass rotor). Changing rotor speeds between fast and slow creates a steady stream of tonal shifts that players have long used for expressive effects. The RT-2 authentically replicates these audio behaviors, coupled with two-way speed control, a Rise/Fall Time switch for adjusting the transition time between speeds, and a colorful indicator that shows the current rotation of the virtual rotors.
