I think the other thing that happened too was, cause of the amount of rock guitarists out there, it was getting to the point where so many of em were applying we couldn't keep up with it.
As hosts we had to listen to each one and vote on em & I don't know about the other guys but I remember one time spending a coupla days downloading sound files & reading so many tabs I couldn't remember who was who.
I'm sure if a rock guitarist came along with exceptional abilities 'far beyond those of mortal man', he'd get in no problem tho...
