Howzit guys,
Below is the "Imprudence Engine" - (Yep I'm getting better at hipster names!)
It's the same Sample Rate Reducer pedal I did a while ago with 2 changes:
1) New graphics :D
2) 2 DC jacks
I had intended to add a small vero board bipolar PSU to convert a 12V AC input into the 2 required 9V connections.
However, after some consideration, it wasn't worth the effort and I'll always have 2 isolated power output anyway.
Check out the video: :D

Also for those who want to build one, here's a verified layout I made:
http://sonictitanfx.com/2012/11/22/bugcrusher-etch-bugbrand-sample-rate-reducer/
The link is to a layout to etch, I did this one on perf but the etch layout is all verified :)
Also watch out - the AD781 chip required is R200 a pop!
Kind regards,
Matt.

Looks and sounds awesome! Got me inspired to build one in some point after all the other things on the work bench are finished. I have to say the board layout is a bit messy and a bit hard to read for a rookie when some of the values and markings aren´t shown clearly. Still very nice!
Are you getting any oscillation bleed through on yours? I built one based on the vero, sounds great, but even when bypassed it was getting bleed through to the audio. Ended up having to short the 40601 when bypassed.
No bleed through when bypassed fortunately.
I think making sure the oscillator wires are as far from any audio wires makes the big difference.
