Product Details

Smooth 16:1 gear ratio, with a rear thumbscrew to lock the string. Single pin mount keeps tuner from rotating, no mounting screws needed.

Staggered string posts:
The Schaller Locking 6-in-line tuners feature staggered string post holes. The tuners with the holes higher above the face of the peghead are used on the E, A, and D strings, and the shorter hole posts are for the G, B, and E strings. This allows the strings to have a steeper angle off the nut than with traditional tuners — eliminating the need for string trees.

Great tuners - some drilling may be required.

By Steve H from Merrimack, NH

I bought these for a 2013 Fender Standard Tele (MiM). I hoped it would just be a few turns of a socket wrench and done. No such luck. The stock Fender tuners have two posts to anchor them; the Schaller has one. So, you need to drill a hole for each. It's not a big deal - just keep in mind that it's not a 5-minute swap. But once they're in, you can change strings in a fraction of the time - no string-winder required. Sweet!

Excellent tuners

These tuners is the real deal. I've replaced all Fender original tuners with those. Couldn't be happier!

Better than Sperzel

Yet another set of Schallers

I've probably gone through a dozen sets of these locking tuners. I upgrade every guitar that I get (With the exception of the Gibson L5) with these locking tuners. My most recent set went on a Warmoth custom neck which I installed on a hot-rodded Roland Ready Strat.

On a Strat and a Tele I really like the two height posts which eliminate the need for string guides, but I suppose if you had a tilted back headstock you wouldn't need them,but would it hurt anything? I never have done a headstock like that and used 6 inline ones.

Anyway thumbs up on the Schaller Lockers

I LOVE these tuners, but here's what I don't like about them first. I have the 6-in-line set, and the posts are different heights! They should make that an option. Not everyone puts these on a tele/strat. It's not a deal breaker, but it bugs me a little. And, they are a little heavier than non-locking tuners. On a marginally balanced guitar, it does make a little difference(almost nil).

Okay, time for the rave instead of rant: They are SMOOTH as silk! 16:1 ratio is really nice. The locking feature saves so much time, and is so much more stable than wrapping strings. They are built like a tank, and look awesome. I guess next time if I don't want staggered posts I'll buy 2 sets, and mix & match so my tuners don't look weird!
