A lot of people like the vibe he puts into his guitar playing and that's cool, but I don't think he is playing anything that a lot of guitar players are capable of.
If Tremonti's style is what turns you on then thats cool!
I do not like his guitar style to much!
So I don't say he is a bad guitar player, he's just not the type of guitarist I like.
To each there own! :)
