I was looking to buy either, and was wonder which one people preferred?
The Morley Classic Wah isn't very good, I used to own one. It sucked tone big time and the sound was really really weak and just too trebly, and had no range or depth. Never tried the AWP-1, but you should try them out and see which one you prefer. If you want a creamy wah sound look at Vox or Dunlop crybaby.
