Roto Sonic – Back for another spin!

These 2022 Roto Sonic pedals will be hand-signed by Robert Keeley. Begins shipping on or before 07-06-2022.


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


Each 2022 Roto Sonic will be hand-signed by Robert Keeley.


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.
