"Best shred moment: Guitars Suck
Having released several albums under the moniker Bumblefoot, Brooklyn-based shredder Ron Thal took over the Guns N’ Roses guitar spot in 2006, replacing Buckethead. A master of almost every aspect and style of guitar playing you can name, Thal is most notable for his playing with a thimble worn on the fourth finger of his picking hand, which he uses to tap notes above and beyond the 24th fret with amazing accuracy"
