HI guys.
I perfed up the ROG Double-D this week and just got the CD4049UBE from Steve at Smallbear today - the Jiggle channel works great - the Bounce channel doesn't make any sound at all.  Here's what I used: http://www.runoffgroove.com/doubled.html.
Anyone have any nuggets of wisdom where I should look here?  I assume from ROG's perf that my problem is in the components on the 'bottom' of the IC...but after going over them for a couple hours, I'm still baffled. 

Thanks for looking.
Mike

Since your jiggle channel works that means everything up to that point is wired correctly, Maybe you could go back and check your wiring at sw1a..going to the bounce

Another cold joint  :icon_evil: - time to get a new soldering tip, I suppose!

Now I have to figure out what to do with the Double-D.  Jiggle is pretty nice - wide range.  The Bounce channel pretty much starts with the 'all dials pegged at 10' sound and goes from there - fun stuff.  I want to box it up in a 125B...should be a good challenge...

Thanks for another fun design ROG!

should fit in a 125B no problem - i put mine in a 1590B which is even smaller.
the double d really is a cool circuit - i love the bounce channel.
i use it with bass so one day i´m gonna mod the jiggle channel for better bass response to get that chris-squire-sound.

cheers,
