MEEP super duper three mode filter effect (envelope/wah/modulation)

[Tuemmueh]

I drew up a schematic following your instructions, letsgocoyote.
Thanks for sharing your informations with us!

I added a little v+ -filtering to the lfo, this might help keeping the noise out of the audio path ... but I'm not sure

I released rev2 of the schematic so the old link isn't working anymore ....
here is the new one:

Little update, nothing fancy ... I double-titled the ICs. Stupid me.

R13 should be 2.2k, right? I've been debugging and ran across that in the schematic.

[Tuemmueh]

in the ggg-schem it's marked as 22k. Maybe I missed some other infos?!

Regarding the depth control, I think you could replace R21 in that latest schem with a 1M pot plus a 10k resistor and you'd have a depth control that doesn't get all asymmetric and clunky when you adjust it.
