The Boss RT-20 Rotary Sound Processor is a twin stomp-box pedal which uses the breakthrough COSM (Composite Object Sound Modelling) technology by Boss. It's function is to create authentic vintage rotary speaker sounds and add additional overdrive into the mix. The RT-20 is based on classic Rotary speakers from the '50s and '60s and each sound can be adjusted easily using the 'Rise Time', 'Horn' and 'Bass Speed' controls.

The RT-20 has 4 main sound types and an adjustable mix between treble and bass rotor. An in-built digital display provides a visual reference of the virtual rotors. The RT-20 is just as effective with either guitar or keyboards/electric pianos.
