Hammett doesn't even do his own switching on stage... his guitar tech does it all from his little hiding spot inside the stage. I saw them live in Indianapolis last summer and the guy doesn't have to do anything but play. He did play an intermission solo for about 8 minutes and only used the wah for about 2 minutes out of the entire solo. I was in the 3rd row and saw it all pretty upclose. but for real...Hammett vs Slash....... who the F cares. I live GnR and I like Metallica... they're both great guitarists... Hammett uses his wah too much... I can play more scales than Slash... it doesn't matter. Becuase They both make money playing guitar and they're both rock icons. LET IT GO. opinions are like assholes, everybody has one.
