Re: Fixed wah pedal... wah effect...?
I believe the Q-Zone is simply the GCB Crybaby circuit in a pedal. The "Q" knob is the same as moving the foot rocker on a wah. It's not an auto-wah, it's just like leaving your wah in a fixed position.
If you're looking at auto-wah's, the Digitech XSW synth-wah has some great auto-wah settings, along with envelope filters and analog synth sounds, all of which can be triggered dynamically.
