I like it because it sounds a bunch like Jerry Garcia and Grateful Dead...........classic sound!! Jim C.

Wahhhhhhht a great sounding pedal.  Yes, there was some Shakedown Street flavor in that sampling.

Thou knowest my desert island pedal is a wah (with Q control and boost please).  Now how can I resist a very reactive sounding auto-wah?

Robert, can you expound upon the sensitivity and controls?

The level knob controls the sensitivity. With a higher sensitivity, a lower signal will affect the envelope’s effect. In other words, with a higher sensitivity you don't have to pluck as hard to make the effect audible.

The range knob controls the range of movement of the envelope’s sweep. Counter-clockwise sweeps more low frequencies. Clockwise sweeps more high frequencies.
