On the subject of wah solos check out "cool #9" and "why" by satriani.
Personally I'm a bit of a treble freak and I probably overdo it with my crybaby wah but I love screaming pinch harmonics. The bassier end I like for fluid scalar stuff.
Does anyone know why wah's so much "wider" in what it control when you back of the gain?
If I couldn't laugh at myself how could I laugh at someone less ridiculous?
