I measured the frequency response from the wah effect, by sending a white noise signal and measured the spectrum at the output.Peak Position (Q) was at 5 and Peak Range (drive was at 0%). The graph is logarithmic and I disregarded everything above 4000Hz. The pedal range was measure only in the negative range, in the positive range toe frequencies are higher then heel.

FYI: I think I got all the related data to create the KPA settings for any given Wah. If anyone is interested, I'll create a spread sheet, where you can look up all my compiled data so far or create your own KPA settings. Just ask.

If you find errors in the sheet, please report.
You have to play with the Peak setting, to get the correct sound.
I also calculated the lower frequency and higher frequency from the given group's Wah settings:

Yes of course. Studied all threads for this, gave me the inspiration for my research.
