It's my first Wah-Wah and it's sounds exactly as I wanted! Clear low-end thickness with smooth high-end fine sharpness with buttery sweetness in the middle. It gets more and interesting as you raise you skills and began to start manipulating the tone. You sort of control which harmonies you want to be squealing, each note has it's own sweet spots (angles). A big reason I bought it was Uriah Heep's guitarist, Mick Box, who is an expert at this. Him, Jeff Beck, Mick Ronson and off course Jimi Hendrix are the ones that this certain "CLASSIC" CryBaby should imitate perfectly - if you have the skill. After 3/4 of a year there has been no practical problems or anything else that has made me unhappy.
