Here is a wonderful Parametric Distortion with the mod for a volume control. The artwork was made by my daughter and I used @chongmagic 's Tayda PDF creator to get it printed. I think it turned out really well.

The hardest part was getting everything crammed in there.

On this, not at all. You just take the effect out signal and run it to pin 3 on an A100k pot, run pin 2 to the 3pdt board and pin 3 to ground.

How'd you stuff it in there? you flattened/clipped the pot tines, and ran leads to the gain and vol pots with dustcovers? I don't see the effect out cut.

since there's no documentation yet. which type of rotary switch does it use?
this one? :

or this one?"

For the volume, this is how I wired it.



I used 9mm pots with straight tines since they're already plastic on the bottom.

I'm assuming that it's the break before make rotary switch.
