ey dude,

Seriously I just got a 7-string myself, but it is honestly no different than using a 6-string. It functions the same way, the only difference is having another B string essentailly. You can get into crazy hybrid chords and such with another string to play another note on.

For metal? What the hell, that should he real easy to do on the 7-string without being remotely tripped up by the extra string. Take it from me it's no different, if you think it is you are mistaken and only limiting yourself to a misconcept.

That might be a little harsh, but it's true.
