Schaller Keystone SR Lock. 3L/3R NI

I bought a Gibson Standard SG 2015 equipped with the GForce robot tuning system. I never got the SG fully in tune with that system. Always had to do manual adjustments afterwards.
Had that and the nut replaced, but... No.
So I thought; fuck it! Lets go old school!
Ordered these Schallers and now my SG behaves lika a guitar should!

I was a bit scared at first. Should I do the work myself? I?m not a guitar-tech by any means, but how hard could it be?
It was rather easy as it would show. Just unscrew the robot and remove it, insert the Schallers. You don?t even have to drill new holes since the screws are very small.
Easy piecy!

Satte dessa på min Gibson Les Paul special eftersom jag tyckte att originalstämskruvarna var lite skramliga och inte gjorde sitt jobb så bra efter knappt 20 år i tjänst.
Det enda som jag kan invända mot dessa stämskruvar är att jag tog för givet att de, eftersom de liknar gibsons delux, skulle funka utan problem som ersättare för dessa. Men, faktum är att stämskruvarna för E-strängarna var väldigt svåra att få på plats eftersom huvudet är lite tjockare i den änden och jag fick byta ut brickan mot en tunnare, vilket var lite av en besvikelse. Dessutom är det svårt att få in strängen i de små hålen på E-strängarna eftersom de sitter så långt ner. Men väl på plats så tycker jag att de gör sitt jobb på ett fint sätt.
Väldig dåligt med instruktioner för stämskruvarna dessutom.

I wanted to upgrade stock tuners on some of my Gibson guitars. These Schallers at first seemed a perfect choice. But then came a big disappointment.

Having read mostly positive reviews, I bought two sets at once. They came in packed in very nice boxes, reminding of a new iPhone. But that's where good things end... Here are the problems that followed:

1. The tuners simply don't fit the headstocks of my Gibson guitars (SG, ES, LP): the supplied shims make the position of the string hole too low to the extent that is it partially blocked by the screw nut that holds the tuner. Well, this can be to some extent overcome by using Gibson's stock shims instead of the ones that are supplied with the Schaller tuners. Yet the sting holes remain too low (which is ridiculous given Gibson headstocks are all angled and do not require directing strings downward as Fenders do). As a result, I could barely put the bass E string into the hole in the tuner (it was a 0.46 gauge). So, if you use thicker strings, for sure the low E string would not come through.

2. The 1st E string could not be clamped in position properly and kept creeping out of the lock (as I was turning the tuner to tune up the string, the tone remained the same or even dropped as the string was slipping out of the lock).

3. Upon installation, all strings did not stay in tune even after a couple of re-adjustments. Compared to Fender locking tuners, the difference in the tuning stability is huge.

4. One of the tuners was outright defective (too loose).

Thus, I'm sending back both sets, which to my regret Thomann will have to handle somehow with Schaller.

And, quite obviously, I cannot recommend this product because, in my opinion, it is a total fiasco. Alas.

Overall, I now consider Schaller products as poor quality and not Gibson-friendly, as the whole situation reminds me of Schaller strap locks whose installation on a Gibson guitar is similarly a big problem, especially with the screw in the lower part of the guitar, let alone other well known issues with these locks.

That's not what we, guitar lovers, expect from the stereotypically superb German engineering. Period.
