The New Standard in Rotary Speaker Simulation!

From the Beatles to Jeff Beck, Santana to Stevie Ray Vaughan, many guitar greats have embraced the rotary speaker sound onstage and in the studio. BOSS proudly announces the newest member of its Twin Pedal series - 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 seed, Overdrive, and more. And not just for classic twirl, the BOSS 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.

BOSS RT-20 Rotary Sound Processor at a Glance:
  • Classic rotary speaker sounds using COSM technology
  • Easy to connect both guitars and keyboards
  • Stunning virtual rotor display

Classic rotary speaker sounds using COSM technology
Years of intensive research and development have made Roland and BOSS world leaders in modeling technology. Roland's breakthrough Composite Object Sound Modeling (COSM) uses the advantages of multiple modeling methods, and succeeds in accurately emulating existing sounds as well as producing sounds that have never before been created. With the BOSS RT-20, COSM is used to simulate classic rotary characteristics, and beyond. The virtual horn and bass speaker can be independently adjusted, while the BOSS RT-20's unique graphic display provides a real-time view of the rotation pattern and speed.

Easy to connect both guitars and keyboards
Guitars and keyboards alike can be plugged into the Easy to connect both guitars and keyboards. Use the Drive Type switch to optimize the effects for guitar or keyboard. Surround your listeners in animated sound with the RT-20's dual outputs, which enable true stereo effects. Add color by adding an expression pedal (such as the new BOSS FV-500H/FV-500L, optional), which lets you control parameters such as rotation speed seamlessly from slow to fast in real time. The BOSS RT-20's phone jack is handy for private practice and experimentation.

Stunning virtual rotor display
Thanks to its stunning visual display, the BOSS RT-20 might be the most eye-catching pedal in BOSS history. The spinning lights don't just look cool, they also show the audio-rotation characteristics of the RT-20 in real time. The center of the display, illuminated in red light, represents the virtual horn. The outside ring, illuminated in blue, displays the rotation of the virtual bass speaker. It's attractive while also being informative!
