• Image of Mad Doctor Stutter

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 there is less on and more off and gets rad and blippy. Back the -RATIO knob off and it results in more ON signal and less OFF. 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.

$7-US, ($12-Canada/$20-International not including potential VAT or Customs fees)
