Countless guitar heroes have embraced the rotary-speaker sound on stage and in the studio. With this in mind, BOSS proudly announced the newest member of its Twin-Pedal family: the RT-20 Rotary Sound Processor. Employing COSM modeling technology, the RT-20 authentically reproduces classic rotary speaker sounds, and beyond. It offers adjustable Rise Time, Horn and Bass speed, and Overdrive -- and not just for classic twirl -- the RT-20 can be used to create unique overdrive and pulsating effects as well. This pedal also offers a stunning graphical view of the virtual rotors on its built-in display.
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 RT-20, COSM is used to simulate classic rotary characteristics, allowing the virtual horn and bass speaker to be independently adjusted.
Guitars and keyboards alike can be plugged into the RT-20; 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/-500L, optional), which lets you control parameters such as rotation speed seamlessly from slow to fast in real time. The RT-20's phone jack is handy for private practice and experimentation.
Thanks to its visual display, the 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 bass speaker. The outside ring, illuminated in blue, displays the rotation of the virtual horn. It's attractive and informative!
