if i were to replace the sweep cap in my vox wah wah with a variable capicitor, could i adjust it so it could function as a bass wah or a guitar wah? if so what capicitence should the cap be?
I'm no expert, but I've never heard of someone doing this. Do a quick search (which you should have done anyway) go into the wah-modding thread and flick through it. If you can't find what you're looking for then ask, and hope someone knows. There are some pretty damn intelligent people in there.
