From the post
Without the pseudo-balanced output and adapted to work as a stompbox. Not really sure if this is worth a build as it is supposed to be not that loud. Simple design with low parts count, so it might be nice thing to experiment on... The pot tapers are not mentioned on the schematic i found, but i suspect that linear should work well enough for both.
