Pearl/Vorg Warp Sound

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.

      There's a typo on my part. Sw3 from the board goes to Sw2 on the switch diagram. Sorry for the confusion.

    Does the trimpot control the gain? I'm seeing a few clones of this(like in the video on this post) with a distortion pot. Just wondering if I could wire in an offboard pot instead of the trimmer to do just that?
