Boss RT-20

Rotary Sound Processor

Leslie - the heavy box with the rotating speakers - is indispensable for the Hammond organ, and many guitarists have also incorporated it in unforgettable sounds and hits: The Beatles, Carlos Santana, Jeff Beck and many others.

A real Leslie is heavy, expensive and rare. A simulation is small, light and affordable: Here comes the BOSS RT-20 Rotary Sound Processor, a further development of the Roland Leslie Simulation (from the Roland Organ VK-7, VK-77 and VK-8), which was highly praised by many Hammond players for its authentic sound.

In terms of sound, features and price, the RT-20 will leave the few competitors behind the Leslie simulations far behind.

  • Authentic Leslie simulation by COSM modelling
  • Four sound modes
  • Integrated overdrive for guitar or keyboard
  • Speed ​​adjustable
  • Large VIRTUAL ROTOR display
  • Effect and direct signal separately adjustable
  • The TIME for reaching the fast speed (acceleration time) or the switching back to the slow speed (deceleration) can be set = RISE TIME
  • Stereo inputs and outputs

Wonderful rotary pedal for guitar and keyboard!

14.08.2014
Really fun pedal that makes wonders with organ sounds, and magic with guitar.
The only thing I would have liked added would be some kind of EQ possibilities, then everything would be on a 5 grade.
Easy to use and operate. The lights are a little bright, but it makes it easy to see status.
The different rotary styles really make a difference and all of them are useful for different songs and instruments.

Kinda in Love

08.01.2017
First off i just wanna say that I'm nether a big fan of Boss pedals or Pink Floyd so one would assume this particular pedal would not be up my street.

I came across it by chance on Youtube while checking out another pedal but was captivated by the spacey sound of this one (for anyone interested just type in 'double muff rotary ensemble demo').

I love it more than any other of my effects right now. I haven't gone through all the settings in detail but so far I Iove just the core rotary sound you get from hitting the right (slow/fast) switch. With a few tweaks to the settings I could imagine dialing in that sweet George Harrison 'Let it Be' solo sound. As mentioned this pedal is popular with many Pink Floyd fans as Gilmour used Leslie speakers extensively throughout his career which this pedal attempts to emulate.

Also, have to mention the epic visual effect at the top of the pedal which represents the rotary speed. I like to play with the light off in the room just to see how cool it is.
