So basically it's another Tube Screamer?

Reviving this old thread. Is this verified? Thought this pedal had buffered bypass but I'm not seeing that here.

Yes, I can verify this schematic and vero layout. The first version was true bypass, then Durham shifted to buffered bypass due to switch popping. This trace shows the true bypass version, you can mitigate the pop quite well with an input pull-down resistor (1M to 2.2M) to ground before R3, plus the Jack Orman LED soft turn-on mod (http://www.muzique.com/lab/led.htm ).

As drawn in Modman's schematic, the bypass is neither true nor buffered, but rather good old tone-sucky always-connected-to-the-input bypass.
