as is typical of me, i will ignore what your asking about and recommend something completely different :D
I tried a plutonium chi wah wah recently and was VERY impressed/suprised, very tweakable too which i don't believe the morley wah has the capacity for. That being said, while i've not played one, i've heard nothing but good things about the lynch wah.
Edit, whoops, not entirely right there, the morely wah is tweakable. Ignore me.
