Yes, on scene 2, I didn't want the wha ; in the original preset (the one I wanted to use for a gig, finally I didn't play because of fever), I used the same expression pedal to control the delay block input gain in scenes 2 and 5 to 8. I removed all these subtleties for the GoT preset to make it simpler for the general user.
If you put the wha control to "all" instead of channel A, you'll also get wha on the clean scenes, and I didn't do that, the wha tends to distort the clean sounds. That's why these scenes uses channel B, where the wha control is ineffective
