After trying to get my wah to sweep a little better (the wah seemed to sweep almost instantly between bass and treble, very very sensitive to the touch), I tried various mods to make it sound better and make almost every position useable.

1.Changed C4 to 22n polyester cap (tried orange drops 715p in this position, it started oscillating in some settings, and 15n osscilates like hell with any cap i tried with some settings).

2. added the freq pot (the wah sounded too boomy to my ears without it.

3. added a pot for R4 (1k pot paralleled to 560ohm almost), so i can adjust the gain.

4. peak pot on the outside (makes some unusable settings, usable)

5. ICAR pot (Area 51).

6. Changed C1 to 22nf.

now the wah sweeps like it should (IMO) and sounds awesome in any setting.

I can do a demo, but only on friday and then i will post a build report and some pics.

i increased c4 again to 220n, it works better that way in the higher gain settings.

forgot to mention that :)

Hah! Good thing I decided to socket all the tweak-able components (including the trannies).
