I'm off for a couple weeks, so I figured now is the time to do a couple mods to my Lakland 55-02 Dlx.
In a previous post, I commented on the factory HipShot lic. ultra-lite tuners. They seem "touchy"...meaning: as I'm tuning up, once I get close, it seems like about a 1/16 -1/8 of a turn and I'm too sharp.

Someone suggested I replace the factory plastic nut.
Any suggestions? The nut width is: 1.78.
Also, I measured the spacing at the nut with a dial caliper and got the following measurements:
B-E=.338
E-A=.350
A-D=.335
D-G=.322
These are from c/c of strings, directly over the nut.
Is the bottom of my Lakkie nut flat or curved?
Thanks!
