I've been playing guitar for two years or so. Until recently, I've been playing a lot of blues and the like. Then I played some metal (ozzy,iron maiden,etc). Now I'm trying some hendrix and I figured I should get a wah. I've figured out how to do the basics, but a lot of sounds I assume are comin from the wah in many different songs I just can't get. Any advice? (tricks, places to learn, etc). thanks.
