From the post
Should be pretty obvious what this one is based on but people rave about it and it does have subtle differences in the schematic, not least of which the clipping switch, that will make this one a worthwhile build.
I'm not sure if this is the official John Landgraff's description of the pedal, but it was the only one I could find:
Bring home the John Landgraff Mo D and watch as your strings bring out a totally new kind of sound. This Landgraff distortion pedal gives out legendarily amazing sounds of distortion effects. With a 3-position selector switch, this vintage distortion pedal allows you to choose between 3 varieties of distortion to enhance your strum. This Landgraff distortion pedal is the second pedal to be created by the leader of pedals and amps, John Landgraff. Users have praised this vintage distortion pedal as giving out simply outstanding, creamy distortion, without a background buzz, characteristic to many other amps. The John Landgraff Mo D will give you distortion like never before and leave your audience craving for more!
