Keeley's Dyno My Roto tri-Chorus Effects Pedal delivers those sought after 80 s vintage rack chorus sounds we all know and love. Keeley has also added a Flanger and a Leslie Cabinet simulator to bolster this pa;ready great package. 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 voice, one straight and one modulated. This offers twice the amount of joy by modulating another voice. Keeley adds Proximity Control to its Rotary Cabinet package. This control simulates 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. Keeley also includes a RotoFlange sound that has a simple negative feedback control. Easy to use and gets you the most classic flanger sounds possible.
