Hello, I would like to mod my wah pedal (Dunlop Cry Baby GCB-95) to make it have a unique sound to me. I would like to know what would allow me to change the wah tone to make it really dark and clear on the bass but have a nice and full sounding treble side. I prefer it to sound more vocal than nasally and throaty and I want the wah to be the same easy design with all the wiring/parts inside the casing without any switches except the on/off. Any suggestions?
