This is an issue madbean documents in the build doc, but I'm having trouble beating it.
At higher gain or bass settings the motorboating goes nuts. Lower gain settings seem fine. It works up to like 75-80% of the gain knob.

I tried toying with some cap values, increasing the decoupling on Vb to 220uF. No luck. Any tips?

I removed C12 and reduced C10 to 470p.

Description from soundcloud:
"Tweaked my Pearl Octaver clone, very satisfied with it now, gonna be back on the board, no need to buy an Octron.
Forgive the hum, I was using my Strat on the middle position, and I'm plugged in the high gain input of my VTM. With the coil tap on, it's the beefiest position on it, but it's got a bit of noise.

Here are my settings:
normal signal: 25%
octave up: 100%
octave down: 50%
two octaves down 25%

Hey madbean, I was making my own wah layout, using your library in eagle. I was curious about how you did your Inductor part. The pad spacing is different than your library. I can't use the default pad size without some overlap. I'm okay with that for my single sided etches.
But I was wondering, should I space my pads like yours? Does it allow both Whipples and Dunlop Fasel inductors to be used?

Not asking for someone to make one, just wondering if there was an etchable single sided layout ever available? If not, I'll probably just make one myself. Just thought I'd ask before I spent the time.
