Hey guys, I got a problem that maybe someone could help me with.

I'm restringing my Schechter Omen-6 Diamond Series. I'm trying out Ernie Ball skinny top heavy bottom strings for the first time. I'm stringing the way I've always strung my guitar but it seems that the strings won't get far enough off the fret board. I've been tightening the strings thinking that eventually they would, but they just keep getting higher pitched and buzzing from hitting the fretboard.

Any ideas on what could be going on? I've only tried with the bottom two strings because I don't wanna **** up the rest of the strings accidentally.
Thanks, I never thought of that. Probably because I've never had to do it before.
