Jimi Hendrix: "Voodoo Child" 8)
started learning it too and it ain't as tough as I thought it would be ;D
You using a Cry Baby?
I used to own a newer Cry Baby, but I traded it in for a George Dennis Optical Wah because the Cry Baby had a REALLY noisy pot, all clicky like, and it was too breathy for my liking.
A cool effect if you've got a wah, single coil and octave or pitch shifter (optional) is to select the neck pickup, turn the tone all the way down and open the wah to about half way, and set the octave/pitch so that it's completely to wet (no orignal signal, or just a touch of orignal) sounds really cool... almost like a mutant bass.
