You can't say that metal isn't music or has no melody, and few very metal bands need loads of pedals. Generally it's just distortion on and they're good to go. In fact a lot of the 'shredders' are basically playing classical music in a metal way, and even extreme bands like Cynic, Atheist, Naked City and Shining (the Norwegian band not the Swedish one) have clear influences of jazz. Not to mention the entire Folk Metal scene. Listen to something like this song by Empyrium (http://www.youtube.com/watch?v=Dl717...eature=related) you can't say that's not music with melody, this used to make me cry back when I was in a much darker place.
OK rant over lol, here's a picture of me in my only fem sized metal t-shirt, a tour shirt for Deicide that my guitarist got me from Deathfest \m/
