Here are some names come to me when I think of favourite guitarists-
Slash, Steve Vai, Jimi Hendrix, Angus Young, John Petrucci, SRV, Randy Rhodes.

What is difference between Gibson Les Paul Classic Guitar and Gibson Les Paul Studio Electric guitar? What is studio guitar? Why is it so cheaper?

I like Gibson Les Paul Goddess because it is an amazing guitar . It is a lighter weight, and frets are little smaller for little lady sized hands.

I think guitar.com is also a good site. You can watch many videos, music videos submitted by users, payer generated lessons, other sites and bands whatever you like. Even you can chat about it.
