  A few transistors and a dual opamp, Craig Andertons: ''Hip Bass Drum'' circuit.
  Wondering how it works, what it sounds like...

I have 3 populated boards awaiting final wiring and firing up (2 of them built in the 1980's), and one etched a few months ago from a PCB layout posted here: http://electro-music.com/forum/viewtopic.php?t=28447

Another one of those projects waitig for the ever-elusive "free" weekend.

Are there and sound sample around for this one?  I Googled, but can't find anything.

Is this sound anything like the Porchboard Bass?
