Is it safe to use baritone strings on a normal guitar (25.5) ? like 13-62, if I wanted to get really low tunings?
Pain is weakness leaving your body.
yeah, but you might have to file out your nut to make the strings fit, and you'll propably need the truss rod and action adjusted.
how do you mean set it up right?

Like have the springs at the back done right in (i have 3 on atm, with about 1/2 inch from the plate to the wood) for the yellow ones (ernie ball, 10-52 or 11-54, cant remember) which is pretty good down to Bb/A#
