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:
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.
