    Lo Pro Edge-7 Problem: Stripped Nut?

    So I put a Lo-Pro-Edge on a heavily modded RG-7420 and thought it would be an improvement. Overall it was, particularly for the string profile to fret board compatibility but it cannot stay in tune after doing both dives (both forward and back). Most of these problems have to do with the nut more often than not. I went over the list of things here BTW:

    https://www.ibanezrules.com/tech/set..._stability.htm

    And so given the above I suspect I may have some stripping at the nut that is causing problems, in particular where the pressure pads and nut meet. So is the attached photos indicative of that? Only other thing I can think of is maybe a shim is required.

    Meaning you think the pressure pads aren't clamping down enough to keep the string from slipping?

    Yes. I just can't tell if that amount of stripping is to blame here or not.

    How about adjusting the string retainer bar?

    I fooled a bit with the retainer prior to posting this thread. I went real low clamping it down but also not (see photos). The results were the same. I was under the impression they are supposed to look more like I have them now from this video @ 11:05:

    The issue I'm having here is that usually you know when a nut is stripped by the allen screw slipping when you go to torque it down. Is that happening? Because if not, that's not your problem. Actual clamping surface of the pad could be glazed or worn, otherwise your problems are down on the other end of the guitar.

    Oh I see. Yeah the bolt/allen screw sets in place. Hmmm, at the other end. Well, according to the Granville guitar guy lube is essential on the knife edge. That I haven't done. Other than that I think the studs are stable. Its a new unit so the knife edge is not worn in anyway. I guess lube it up? I haven't gotten a syringe yet to do it but I guess that's what I should be looking into now.

    The studs are new too? I get gouged studs sooner than rounded/chipped knife edges typically.
