Well you're on HR so i think there's enough info provided here that'll get you from cd to the computer.
I have an assignable volume/wah on my pedal board also.I love it.I assign it to my lead channel so when i pull back on the pedal,it'll turn my noise gate off,give a slight volume boost,and add delay.
For my rythm i'll set it up just to off the gate or on another program # i'll have it set up to turn from dirty to clean while adding chorus or flange.Depends on the song.I don't use the wah on the pedal board though.I like my bad horsie better.I just like the functionality of being able to turn on/off 3 seperate effects at once.
