BOSS RT-20 overview

  • 1Description

Add some classic rotary speaker tones to your guitar or keyboard rig with the BOSS RT-20 Rotary Ensemble Pedal. The rotary speaker sound has been adding mojo to guitar sounds over several decades, gracing countless recordings from the Beatles to Joe Bonamassa. The RT-20 is modeled on the famed Leslie 122 speaker, and recreates those legendary tones, but without the bulk and weight of a massive rotary cabinet. Rather, you can place the RT-20 in your guitar's or keyboard's signal chain and enjoy the rotary speaker effect on your tone. Four modes are offered, ranging from a traditional rotary speaker effect to a classic '60s/'70s Uni-Vibe type effect. You can even add some grit by using the Overdrive control. The RT-20 can operate in mono or stereo, and has a connection for an optional expression pedal (sold separately) to control the rotor's rotation speed in real time.

COSM (Composite Object Sound Modeling) Technology
With the RT-20, COSM is used to simulate classic rotary speaker 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
Versatile Connections
Guitars and keyboards alike can be plugged into the RT-20 by using the Drive Type switch to optimize the effects for guitar or keyboard. Surround listeners in animated sound with the RT-20's dual outputs, which enable true stereo effects. Add color by plugging in an expression pedal (such as the separately available BOSS FV-500H/FV-500L), which lets you control parameters such as rotation speed seamlessly from slow to fast in real time. The RT-20 also features a headphone jack for private practice and experimentation
Virtual Rotor Display
The eye-catching Virtual Rotor Display show the audio rotation characteristics of the RT-20 pedal in real time. The center of the display—illuminated in red—represents the virtual horn speaker. The outside ring—illuminated in blue—displays the rotation of the virtual bass speaker
Rugged Design with Flexible Power Options
The RT-20 can run off of six AA batteries or an optional external 9 VDC power supply. The electronics are encased in a durable dual-pedal metal housing with a non-slip rubber base. This pedal utilizes a buffered bypass for silent switching and driving long cable runs, even while the pedal is disengaged
