Problem with Grover 406c
I recently upgraded my SE custom 24 with the Grover 406c. I love them except I keep breaking the first string after light trem use. I've gone though 5 new sets after about an hours worth of play time. The strings always break at the tuner post. Has anyone else had this problem or have any recommendations?
Nut Sauce for the nut slots?
Get a needle file and round the edge of the hole in the tuner post a little.
Or... go back to the PRS tuners.
I have had a similar problem with the non-PRS Gotoh locking tuners that share the same basic design. I would check to make sure there are no burrs in the hole of the tuner, and if so use a jewelers file LIGHTLY to smooth things down. It is important to not over-tighten the the locking barrel so hard as to cause a crimp at the little pin that is under the barrel. Best of luck, it was an infuriating experience to snap through all those E strings.
Thanks everybody. I went ahead and lubed the nut and filed the tuner with a serrated knife sharpener. My guess is that it is similar to a file like was suggested, it seemed to work perfectly. In addition I decided to switch the E and G string tuners on the headstock. So far with a good jam session last night the E string held up. I'll keep you posted if I have additional problems.
