Roto Sonic – For the first time in our ‘Blackout’ colorway

These 2022 Roto Sonic pedals will begin shipping on or before 09-08-2022.

The Roto Sonic Rotary Speaker Simulator offers three distinct modes: Les’, Vibro-S, and UVibe.


The Keeley Roto Sonic features three Dopple-Swirly-Vibey sounds! It’s a three-mode pedal with custom crafted rotary speaker effects. The three modes are Les’ Rotary Speaker, Vibro-S mode, and U-Vibe. Fill the stage with organ tones as rich as a dark lacquer. These Doppler effect tones are based on vintage speaker cabinet designs. So dead on perfect, you’ll swear you can hear the motor Wurrr. Keeley’s DSP has taken these vintage speaker and rotary sounds to a higher level.  The Roto Sonic is amazing in detail and nuance, and not just another chorus of bad sounding phasers.

Add some spin to your signal with the Keeley Custom Shop Roto Sonic.


The Roto Sonic features three of Keeley’s mind spinning sounds that are often heard on recordings, but rarely heard from a guitar player’s live rig. How often has this happened to you? You’re the hot new player in a band, and you still don’t have a rotary speaker cabinet sound?! You show up at the gig and here comes that part Leslie used to play on the organ, and now you need THAT sound!!! You don’t have to go to the Dark Side anymore for Keeley’s shiny diamond; it’s now here as a stand alone.
