it could be coz of vibrations from the note...

and yeh, guitarprinciples won't help a lot with the use of picks, and u do have to mute the strings not being used,

and hey, i have an ibanez gio 2! although i've modified it that much i dunno if u could call it that nemore, they r great and real easy to playn i reckon, good learning guitar ;)

rock on
