Keeley Dyno My Roto
Keeley · pedal
The Keeley Dyno My Roto packs lush 1980s rackmount-style modulation into a pedalboard stompbox, combining tri-chorus, rotary speaker, and flanger effects with shared analog warmth. Controls for Rate, Depth, Texture, and Blend shape the sound, and the Texture knob unlocks three LFO shapes, from smooth swirling sine-wave chorus to sharper triangle motion and a stuttering square-wave tri-chorus. It excels at rich, dimensional chorus and authentic flange tones, with a rotary speaker simulation included for Leslie-style movement. It suits players chasing vintage 80s clean tones, ambient textures, and shimmering modulation. The flange and chorus voices are its strongest, while the rotary mode is serviceable rather than class-leading.
