Tiltback headstock & Floyd Rose Nut - Need a retainer bar?


Active member
I have two tiltback headstocks with Floyd nut prep. Will I need retainer bars on them or is the tilt back sufficient? I want to avoid that issue where the strings go sharp as you tighten the locks.

I am planning on Hipshot tuners on one and plain Jane Gotohs on the other, if the height of the tuner post matters. I’m thinking no, but I realize I don’t have one in the pile ready to build.
