Always wished my Budda wah had a bit more of a useable sweep (more treble). Lemme see if I can explain this without being confoosing: Assuming all wah's are the same, there's the shaft with teeth connected to the pedal that rolls the pot when you rock the pedal back and forth. The pot has more play than is used so I simply moved the shaft off the pot (extremely simple) and rotated the pot a tad more to the treble side. Using this example, let's say the wah, heel down & tilted back, didn't start the treble kicking in until half way down now kicks in sooner. I guess the whole point is you CAN adjust your wah's sweep to possibly get it where you want, sure is a helluva lot cheaper than buying mod kits.
