@leandro... true other guys do use a WAH but sparsely in most cases... Kirk is a WAH abuser... and the reason the Wah is a (usually stupid effect, especially on lead... it's cooler occasionally on rhythm) but basically it dilutes the notes... and makes them nearly impossible to make-out as a listener... basically it's a CRUTCH (if you suck balls at playing the guitar)
So Kirk's music world's most overrated guitarist ever. Extremely discarded technology, repetitive solos and his fuckin wah wah use to hide his mistakes. He plays so crappier that he hurt himself. Therefore, he uses a fucking tape.
He is not overrated and not a wah abuser. I don't see why you people keep comparing him with other guitarists. Each guitarist has his own style. So, all of you who keep talking crap like he sucks, let me know when you'll manage to play guitar like him or write a solo like one of his. And yes, Kirk is my Guitar God!
