Sewer Pipes Ring-VerbVerified
Based on the Sewer Pipes Ring-Verb
From the post
Here's a cool PT2399-based circuit designed by David Edgar (DIYSB member Earthscum). He describes it as, "kind of like playing in a sewer tunnel..." Here's a link to the original schematic and discussion over on DIYSB.
I noticed the schematic image in the DIYSB thread is now broken, so I've drawn up a new one for reference here.
