From the Beatles to Jeff Beck, Santana to Stevie Ray, many guitar greats have incorporated the rotary speaker into their rigs. With this in mind BOSS proudly presents the RT-20 Rotary Sound Processor. Employing COSM®-modeling technology, the RT-20 authentically reproduces classic rotary-speaker sounds. It offers adjustable Rise Time, Horn and Bass speed, Overdrive, and more. And not just for classic twirl, the RT-20 can be used to create unique overdrive and pulsating effects as well. This pedal sounds amazing, and offers a stunning graphical view of the virtual rotors on its built-in display.

  • Authentic rotary speaker sounds via COSM® technology
  • Slow/Fast transition time is adjustable from gradual to rapid change; optional Expression pedal can control speed in real time
  • Onboard Overdrive effects
  • Adjustable mix balance between Treble Rotor and Bass Rotor
  • 4 types of sounds, from standard rotary speaker effects to rock-oriented tones, UNI-V, and more
  • Guitar/Keyboard switch
  • Dazzling virtual-rotor display
