Hello, i've been thinking of this for a while now and i'm scared to try it so i'm asking it here first. I've auditioned for a metal band that is pretty heavy. They use 8-string guitars tuned in F#. The problem is that i don't have any way to reach the F#. If i'd downtune, my strings will be floppy like hell. (Note i only have 4 strings). So i was wondering, maybe i could tune up to F#. Is this a good idea? Will my strings break? Will my neck suffer?
