Keeley Dyno My Roto Tri-chorus Rotary Flange Pedal Review (April 2024)


Last updated on April 9, 2024 4:52 pm Details


In this review post, we’re going to be discussing the Keeley Dyno My Roto Tri-chorus Rotary Flange Pedal, including an overview of its unique features.

Product Description

Do you want tri-chorus in a pedal?  The new Keeley Dyno My Roto!

Finally, you can get those 80’s vintage rack chorus sounds that define killer chorus sounds.  This was not an easy development.  The Dyno My Roto is a tough and difficult thing to accomplish in such a small package and we couldn’t leave good enough alone.  We added a Flanger and a Leslie Cabinet simulator.

The magic to the chorus sound in the Dyno My Roto is the three LFOs that give you lush modulations that truly sing out like a chorus of guitars. Most chorus pedals, in fact nearly all, are simply two voices, one straight and one modulated. This offers twice the amount of joy by modulating another voice. That significantly reduces the ability to just hear one voice being affected and smears a couple of voices in an effect that is truly enjoyable to listen to.

We came up with a new Rotary Cabinet package that gives you Proximity Control.  The Proximity Control controls how far away you are from the spinning speaker cabinet.  This adds depth and distance to the cabinet and is a touch like a reverb control.  It gives you that spatial expanse that can give you presence or depth in the chorus-like rotations.  Lastly, while we were spinning things, we crafted a RotoFlange sound that has a simple negative feedback control.  Easy to use and gets you the most classic flanger sounds possible.

So whether you are going for an Alex Lifeson of Rush tone, an Andy Summers of the Police tone, or an SRV Crossfire rotary tone, we have you covered in one box with the Dyno My Roto.

Our Verdict

Robert Keeley, the pedal master, has released the Dyno My Roto, which he describes as “the finest chorus you’ve never heard.”

The Dyno My Roto seeks to capture the sounds of old rack choruses from the 1980s, but it also has a roto flange with negative feedback control, as well as a rotary noise with adjustable proximity for depth and distance (tweaked via the texture control).

Other controls include the standard rate, depth, and level settings, as well as genuine bypass switching and 9V power supply operation.
