Boss RT-20 Rotary Ensemble
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, and beyond. The virtual horn and bass speaker can be independently adjusted, while the RT-20’s unique graphic display provides a realtime view of the rotation pattern and speed.
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/FV-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.
Virtual Rotor Display
Thanks to its stunning 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 horn. The outside ring, illuminated in blue, displays the rotation of the virtual bass speaker. It’s attractive and informative!
