So im getting Grover locking rotomatics for my les paul.

Anybody had any experience with them? are they good? Do they keep the strings in tune? Just wondering what you guys think.

Epiphone Les Paul Standard
Vox AD50VT
Visual Sound Jekyll & Hyde
MXR Dyna Comp
Boss PS-5 Super Shifter
I do have a set and they work pretty good. But their in strat I built. You dont need a thumb screw on the back of the tuner. My LP doesnt go out of tune with regular grovers. They probably more needed on a guitar with a wammy.
