Sound quality: this guitar comes with EMG's so ofcourse its going to sound amazing! To me this guitar sounds so perfect for Metal, and everything else you can think of.
I put ease of use as a 7 because of the floyd rose. For someone without previous experience with a floyd rose, they really are quite frustrating, but the end result with the whammy bar adds to this guitar's amazingness :D
Which brings me into features, pretty much everything you'd find in any normal guitar, but the floyd rose tremolo adds to alot you can do.
Bang for buck: Most people say, and I agree that this guitar is quite expensive, but definitly worth it, it sounds, looks, and feels amazing to play, the neck is nice and smooth, and it holds its tune well.
