From the post
There have been a few different iterations of the Soul Preacher. This one follows the version that isn't based around an OTA chip (much like a DynaComp), but is rather much closer to an Orange Squeezer. The original used a buffered bypass, and I've included an extra pad for the buffer out if you want to build it that way. Here's the schematic for reference.
