I wish to set my expression pedal up with the VoiceLive 3, so that it can function as a 'normal' wah-wah. How to do this?
In order to get a 'normal' wah sound, first connect and calibrate the expression pedal as you normally would.
Then, go into the Guitar menu of any given preset, find the Wah tab and select the Classic Wah for example.
Then, on the right-hand side, the Hit Control should be set to ON. Scroll down a little and you should find that under HiCut it now says Exp Pedal, and under Type, it should day Manual - if this is so, you can then tweak the Pedal Min and Pedal Max parameters to your taste, but all in all the expression pedal should now function as a 'normal' wah-wah.
