The PWM is great and I can't stop playing with it's weird tones...but I have two issues with it:
1) The LFO omits a clicking sound that's in sync with the LFO cycle when I stop playing. It's inaudible with a clean amp, but it's very loud into a overdriven amp. Is there any way to reduce this?
2) The LFO doesn't go slow enough! Is there a way to slow it down some more?
Danke!

You can try decoupling the power supply with a big cap. Perhaps something like a 470uF cap.

The RC network could be changed. Doubling the size of the cap would probably do it.
Thanks Tim! You give great uh, customer support :P
So you mean increase the 22uF to 470uF, and the 100uF to 220uF or so?
sorry: which circuit would that be?

scroll down about 1/3 of the way. It makes some great microsynth type tones through an overdriven amp. The LFO add-on turns it into a cool robo-flanger thing. This thing is hard to explain!
