Hello, thanks for reading my first post! I bought a GT10b a couple months back but am only now really taking a look at it. I've never had a multi-effects unit, so I'm sure my problem is from being 'green'. Anyway, I've got a good portion figured out, but wanted to set up something with sub wah and control it with the expression pedal. I can't seem to make the exp pedal work. It controls the volume instead. I found (I think) where you directly assign a function to different pedals, i.e. assigning ctl1 or 2 to trigger an effect. I've got that working, but when I assign the expression pedal to sub wah alone the pedal no longer controls the volume (of course) yet the wah does nothing. What am I doing wrong? I could have sworn it did work when I played with it before but can't seem to get it working now. I don't think I've made any changes that should have affected it. Thanks in advance for any help.
