Carl Martin Crush Zone

Here is a simple distortion pedal by Carl Martin.
Original FSB thread and schematic available here.


  1. Sounds pretty nice and mid-rangy. I bet it cuts through well in a live situation. Scoop some of the mids, add a flanger and you might have a close approximation of EVH on "Unchained." I'll put this build in my "maybe" pile for now.

  2. May give it a go over the christmas break. The tone seems to do nothing in the vid until it hits the 9oclock position and the distortion control even less. Still worth a look though

    1. Maybe because effect only uses linear potentiometers, but Gain and Volume should be logarithmic?
