According to R.G. Keen's article, if I put a 1k trimmer in place of the 470r coming off of Q1 (2n5088) to ground, I can reduce low end Oscillation. How would I wire the trimmer, 1 and 3 on the ground side, or 1 and 2 with the ground either not connected or hooked to a ground source?
Pedal building is like the opposite of sex.  All the fun stuff happens before you get in the box.

Victory!!! I removed the wah trimmer and 22k resistor, removed r6 470r and replaced it with a 1k trimmer, tuned out the rest of the oscillation. It's now a very usable wah.
