Setting up a wah-wah on an Axe-FX

Assuming the pedal is plugged into the Pedal 1 input on the back, press I/O, go to the CTRL page, scroll down to External 1, then fiddle with the wheel until it says Pedal 1 (should be the first one). Now you have the expression pedal assigned to External 1, and you can use it to control any parameter that has the little "box" under it. Now, to control the wah, you need to go to the edit screen for the wah, choose FREQ, press Enter, and set the source to Extrn 1. Now your pedal should control the wah. To have the wah turn off when the pedal is in a certain position (heel up or heel down), scroll down to AUTOENG, and turn it on. Fiddle with OFF VAL until it feels right.

Oh, sorry. Slight change: in the CTRL page, highlight external 1, press enter and it should say LEARNING. Now rock the pedal back and forth until it goes away. It should now display a number, which is the MIDI message the pedal sends. Everything else is as I posted before.

Not that much different, just have to find out what CC message is assigned to the wah on the MIDI controller, then assign that value to the External controller in the Axe IO menu.

You don't actually need to know that. Just use the LEARN function and the Axe will take care of it. I forgot about the LEARN thing, since it's been more than a year since I've had to touch any of those settings.

put it in the loop? the loop block can be moved around like the rest right?

Yep, you could try the wah in the loop. Then you can route it however you want.
