See I'm not sure if it's a dig at Tommy, the people who keep comparing Tommy and Duff or both 
Either way Tommy is awesome it sucks that some people are making G&R fans look like a bunch of overly defensive clowns, myself included.
Just say I suck, its okay

He doesnt suck, its just in GNR he hasnt really been allowed to do much at all-the Blues is about the only song you can actually hear bass on and live he mostly covers Duffs work.
So as far as GNR goes, I cant rave over him-even if I wanted to.
