I dont know really, but Joe Satriani does it ALOT, and so does Herman Li. The reason they mute the strings is cause so the other strings dont vibrate while, sweeping, trilling, pull off, hammer, ect.


(??picking hand muting the strings between the fretting hand and the headstockof the guitar??)


yep thats what I'm talking about, well i dont know if its sweeping or not, but could I have some advice if ya dont mind
