sounds like the filter from the MFOS Wierd Sound Generator to me, Theres some information if you do a search on this forum or have a look on the net. Theres plenty of people who have drawn out standalone schematics for it.

Here's a schematic for that filter (only the stuff on the right side of the dotted line). I have breadboarded it and it works pretty well.

so if i connected a 1/4 jack to the input, one wire would go to ground and the hot lead would come before R7?

thanks for the schematics!

You got it. You will likely need to vary R7 depending on the signal you feed it. I think I actually just left it out.
