I have an original crybaby that I've done a few mods to, and it sounds pretty nice. but I want it to have that Hammett "woaahh" sound rather than that sharp "waah" sound that mine has. So if anyone has the KH sig wah, I'd appreciate some schematics or a picture of the guts so I can see how mine is different and if I can find a few parts to replace so it sounds more like it. Thanks
