Keeley Electronics Dyno My Roto Maker: Keeley Electronics Model: Dyno My Roto - Tri Chorus, Roto Cab, Flanger Condition: New Description: Finally you can get those 80’s vintage rack chorus sounds that define killer chorus sounds. This was not an easy development. It is a tough and difficult thing to accomplish in such a small package. And, we couldn’t leave good enough alone. We came up with a new Rotary Cabinet package that give you a Proximity Control. The proximity Control controls how far away you are from the spinning speaker cabinet. This adds a 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.
