I'm genuinely curious, is Tremonti a highly rated guitarist?
		
		
	 
Yes, he is. I'm not sure what you want to see as proof, but I can gather a list of reputed sources that speak highly of his guitar playing and songwriting skills once I get off my phone and reach my laptop. I can't speak about the technicalities, of course, but I can say why I think he is so good.
He's entirely self-taught, which means he has a very distinct style. Yet, he's extremely versatile. Even though he's mostly known as a "shredder", his playing is always very melodic. He always claims that melody comes before everything else, which makes his sound very pleasing to the ear. Also, he's very level-headed and focused and continues to challenge himself constantly, developing both his songwriting and playing over the years, not resting on his laurels or accolades. Last but not least, he's very inspiring (to me, at least) and is just a great role model. As I said, my point of view is purely subjective, but this is what the idea of the poll is anyway.
