Schaller Keystone SR Lock. 3L/3R NI

Halpis-lespaulin omat virittimet hurttas, eikä pitäny virettä. Aloin etsiä tilalle parempaa. Minulle suositeltiin yhdestä lähteestä tätä valmistajaa ja toisesta lähteestä lukkomekanismia. Aikani haettuani, löysin nämä laatuun nähden halvat tunerit. Tosin ostaessani, asentaessani, enkä vielä kieliä vaihtaessa tiennyt oikeasti, miten nämä toimii. Sain neuvon, että kieli läpi, vedä löysä pois, ruuvaa lukko kiinni ja viritä sekä leikkaa ylimääränen pätkä poikki. Kokeilin, hämmästyin, ihastuin ja seuraavaks on vaihdettava vastaavat stratoonkin. Ei välttämättä ole ihan kauneimmat mustaan lapaan, mutta käytännöllisyys menee ulkonäön edelle. Pitää muuten vireenkin todella hyvin. Mahtava ostos, kiitos Thomann!

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.

Fitted them in my LP Studio, replacing Tronical, which replaced stock.
As a bedroom guitarist I practice some blues now, so I bend a lot. In spite of it the tuning is quite stable and usually needs only minor adjustments before play.
If you're new to locking tuners, remember not to overtighten the locking pins, or your E wil break :)
Overall - very happy. The only thing which may not be perfect is the color of tuning pegs, which does not match stock
