The Mad Doctor Stutter is not a square wave tremolo. It is an automatic kill switch machine that turns the signal complete on and off. The -RATE knob controls the speed rate of the ON/OFF switching adjustable from really really slow to super super fast, while the -RATIO control slews the amount of ON vs. OFF. With the -RATIO knob maxed and the switch to the right, it gives 50% ON and 50% OFF switching. Back the -RATIO knob off and it results in more ON signal and less OFF. Flip the switch to the left and it reverses the ratio so that there is less ON and more OFF allowing for a more blippy percussive sound. I have had lots of dudes tell me this is the pedal they have been searching for for years because unlike a square wave trem, it totally kills the signal in the OFF cycle. Oh and whats super awesome is that it has an expression pedal input so you can change the speed rate on the fly making for some very interesting and unique sounds!

4.7″ x 3.7″ x 1.18″ enclosure, true bypass switching, common 9v center negative BOSS style power input and battery snap.
