metallica using dropped d?
BAHHAhAHAHAHAHAHAHA.... can we safely say that they have broken away from their roots yet?
As for tuning advice, if your just talking about tuning the whole twanger half a step or a whole step down, then i wouldnt bother unless you want to play along with the record. Itll sound right until you go compare it to the cd.
Then of course, you might be into lots of pumpkins and other bands that have pretty much every song down half a step. In which case, just start learning to tune quickely.. before long youll find that you know the tones to look for without even thining about it.
Oh, and the capo idea is probably not wise if you are just beggining. If you get used to it like that from the start, and then you try to play a guitar without the capo there, all the frets will be in the wrongs spots and youll just freak out
