I'm a big chorus fan, so when I was looking for something a bit different, I had to give this one a try. It does sound a bit unique, which may inspire some, but to me it sounds thin and metallic, not lush and warm. I couldn't get a sound out of it that I liked enough to keep the pedal, so I returned it. I preferred the more classic chorus sounds of the Boss CH-1 or EHX Small Clone.

Keeley's Dyno-My-Roto pedal is like a time machine. As someone who grew up in the 80s and currently plays in frequent gigging R.E.M. and Police tribute bands, I can attest to the pedal's immaculate recreation of the era's sounds. The Leslie sound is good, though I perceive a slight treble dip when I kick it in. The Flanger is excellent, but does not do "Unchained" exactly like the MXR. However, the chorus has everything I believe other choruses lack. It's not the warmest chorus, but the swirly swish it gets is spot-on 80s. Better than every other choruses I've used. And it's not just a chorus, as it has elements of flanger and phaser in it. To my ear, The Cult's "She Sells Sanctuary" is an MXR Phase 100 (maybe, maybe not) , yet the Chorus on the Dyno-My-Roto chorus nails that sound. At the same time, it also nails the beautiful sounds on Cyndi Lauper's "Time After Time." Not necessarily guitar hero tunes, but to someone who grew up on these sounds will appreciate the special thing this pedal does. I use it regularly for all the Police tunes I play, and it's immaculate. The Dyno-My-Roto is a brilliant pedal.

The Dyno My Roto is an excellent, musical and very usable pedal, but it has limitations. The chorus makes a beautiful sound but doesn't have the warmth and lushness of a good analog chorus, like a CE-2 or vintage DC-2. Then again, it has a more complex tonality and nobody expects it to sound analog. The rotary effect is very good. If I hadn't owned an H&K Tube Rotosphere, the Keeley would impress me a lot more. But where the H&K sounded like a Leslie, the Keeley sounds like a Leslie simulation. The H&K has authentic touches like an upper horn spinning separately from the lower speaker and slowing down at a different rate, and the sound is very three dimensional, and it's stereo. The Keeley doesn't do anything like that, but that is comparing it to a tube effect costing several times what this one does. It would be usable in a live setting, but probably fall short for pro level recording. Finally, the flanger is possibly the most convincing effect in this pedal. It sounds very close to the classic flangers with it's resonance and convincing swooshing sounds. So while it is quite a feat to get all these very good effects into one compact box, it doesn't quite achieve the authentic and rich sounds of classic tube or analog effects, but for a compact digital pedal it is excellent, and quite usable.
