From the post
Here's a rare one that came in via the request folder. It's a distortion/filter effect. Used live by guitarist Kevin Sheilds from My Bloody Valentine on "Sometimes," this might be a must-build for shoegazer fans out there.
Here's a demo video of a clone with the 100k trim pot wired externally as a distortion control (which might be a good mod to this circuit.
Not a true-bypass effect–removing the buffer is next to impossible. You can use a SPDT or if you want a LED on/off indicator, use a DPDT.
