The delay times are set so the left a dotted eighth, and the right is a quarter note, both at approx. 116 BPM. This works great if you arpeggiate a chord with eighth notes. Feel free to increase the delay levels for a more drastic effect.
This is basically a Cabinet Random Generator. Crank any of knobs 1 thru 3 to any position and you get a a random configuration of cabs, mics, mic positions, and cab sizes. Takes the control out of your hands to give you combinations you normally wouldn't go for. It's full of happy surprises! Knob 4 throws in Phase combinations to really take it out there!
