Detail 01
Expression pedal format
Speed is controlled by rocking the treadle, so rotary rate changes in real time instead of sitting fixed.

Independent shopping perspective
The Korena take
Dunlop's rotary-speaker effect in an expression pedal. For guitarists who want Leslie-style swirl they can speed up and slow down with their foot.
Strong match
Who this is for
- Funk rhythm parts where the swirl follows your playing dynamics
- Players who want to ramp rotary speed mid-song by foot
- Adding movement to clean chord work without a chorus pedal
Consider the trade-offs
When to look elsewhere
- Players wanting a set-and-forget modulation with knob control only
- Anyone on a tight budget — this is expensive for a modulation pedal
- Small boards — expression-pedal enclosures eat real estate
What matters in use
The specifications, translated
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.
Detail 02
Touch sensitive / dynamic response
Pick harder and the effect reacts, so the swirl tracks your attack rather than running independently.
Detail 03
Rotary vibe voicing
Pitch and volume move together like a spinning speaker, a thicker warble than standard chorus or tremolo.
Detail 04
Foot-treadle mechanism
Moving parts and a rocker mean more to maintain than a static stompbox, and it needs floor depth.
Final check
Know before you order
- 01Confirm power requirements and whether a supply is included before you plan the board
- 02Measure your pedalboard — treadle pedals need more length than a standard stompbox
- 03Rotary sits best after drive and before delay/reverb in the chain
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Is this the same as a chorus pedal?
No. Rotary moves pitch and volume together to imitate a spinning speaker cabinet. Chorus only detunes a copy of the signal. Rotary sounds thicker and more three-dimensional.
02Can I control the speed with my foot?
Yes — that is the point of the expression-pedal design. Rock the treadle to ramp the rotary rate up and down while you play.
03Does it work for funk?
Yes. The touch-sensitive response suits funk rhythm playing, where the swirl reacts to your picking attack on clean chord work.
04Where should it go in my signal chain?
After distortion and overdrive, before delay and reverb. Running it before drive muddies the modulation instead of letting it sit on top.
