Weener Wah Question

[kinski]

Okay, I got the wah tuned in really nicely. Sounds fantastic. But there is one problem that still bothers me.

At an early part in the sweep, there is a static sound, like its a dirty pot or something. The strange thing is, I don't think its the pot that is causing this. The static sound only happens when I am playing my guitar through it. If I roll the vol back on the guitar all the way, and rock the wah, there is no static. Also, I ran an oscillator through instead of a guitar, and there was also NO static sound. But if I use ANY of my guitars, I get that sound.

Its quite annoying because when you are rocking back and forth, you hear a "tsh tsh tsh tsh" sound. I even tried a different pot and I still got the static sound.

Any ideas what this could be? Does anyone else have this problem?

Well, I played this in a live context tonight and it was totally fine. Totally forgot it was even an issue. Might bother me for recording, who knows. Killer wah though!

Hey Kinski.  Don't want to re-thrash this thread but I too had the scratchy pot sound, without it being a scratchy pot.  It disappeared gradually as I upped the 220R to 390 and then even higher 470 until it was gone entirely.  FWIW

Hey! Just saw this, thanks! I did not use a 220k resistor anywhere. Do you mean R4?

Yes, I did the a couple of the popular mods;  in this case taking R4 to 220R for more gain (not 220K).  At that it was the deepest, quackiest wah I ever heard/had, but still sounded scratchy.  I had to give up a little quack for cleans with a 470R but it's till a great wah sound.
