Wah buffer causes slight distortion

[yeeshkul]

Guys how shall i mod the buffer http://fuzzcentral.ssguitar.com/mccoy.php so it doesn't distort the signal?
The distortion is very mild and it happens just at mid range of the wah pot but i wouldn't mind to get rid of it.

Hi.

Replace the FET (from the output buffer) with a MPF102. That would do the trick. It worked for me.

cheers
