Boss RT-20 Rotary Ensemble · Guitar Effect

Artists from the Beatles to Jeff Beck, Santana or Stevie Ray Vaughn have used the rotary speaker sound both onstage and in the studio. Now Boss launch the newest model of their Twin Pedal series: The RT-20 Rotary Sound Processor. Incorporating the unique COSM technology, the RT-20 accurately reproduces rotary-speaker sounds. It allows you to adjust Rise Time, Horn and Bass speed and Overdrive. However, that’s not all yet: In addition to the classic rotary sounds, the RT-20 can be used to create unique overdrive and pulsating effects. This pedal does not only sound excellent, but also offers a stunning graphical view of the virtual rotors on its display.

Features at a glance:
  • Authentic Rotary Speaker-Sounds by COSM-Technology
  • Slow/Fast transition Time can be adjusted from gradual to rapid change; speed can be controlled in real-time using the optional expression pedal
  • Built-in overdrive effects
  • Adjustable mix balance between trebel rotor and bass rotor
  • 4 types of sound ranging from standard rotary speaker effects to more rock-based sounds, Uni Vibe and more
  • Guitar/Keyboard switch
  • Virtual Rotor-Display
