I just picked up a brand-new Dunlop Crybaby Bass Wah. Unfortunately, as I push down on the pedal, I get this crackle-static noise. It happens about a third of the way from back to front (bass to treble). I opened up the case and cleaned everything I could reach. I even put a little extra lubricant in there to make it swivel smoothly. The static noise is still there. Does anyone know what is causing that and if there is a simple way to fix it? It seems like a minor problem that should be fixable with duct-tape or something. Any help would be great. Thanks!!
