ive seen em in a few music shops, they seem like a waste to me. im not a big hendrix fan, but i have a crybaby wah pedal and it works for all wah songs ive heard. i mean, its a damn wah pedal. i honestly dont know how they can charge so much for one. oh wait...i do...its becuase its purple!!! hah, if i where you id just buy a 70 dollar crybaby.
