I finished building Park Autowah using this layout ... o-wah.html (thanks to Anders!).
I like it a lot, but I want to modify to my taste:
1. it sounds a little muffled (I want to have more highs) - I eliminated both 1nF caps to ground (C2 and C5) but with no significant changes
2. the minimum speed it's too high (I increased the 2.2uF caps (C9 and C10), but this decreased a lot the maximum speed).

Thank you!
