Hey
So I built a couple Dirtbabies lately (one for me, one for a friend). Man it's probably my favorite delay so far! I've built a couple delays before but this one is just SO good!
They run on 18v with a charge pump inside (more headroom this way, and for some reason, 9v didn't seem quite high enough, there was some distortion).
I'll post a build report as soon as I take pictures.
Only thing I changed apart from 9 to 18v is C10 (1,5nf) and C12 (150nf) to attenuate the noise. Also R5 is now about 30k (since raising C12 also raises volume)
There's a slam switch (with internal trimpot to decide how fast it ramps up towards oscillation) and a tone toggle switch on top that adds another 1,5nf in parallel with C10 for a darker tone.
Anyways, it's not a proper demo, but it shows a few nice settings!
