Installation is easy, but not obvious

I just want to chime in here to hopefully save somebody the trouble I ran into. I bought the 6 in-line set. The tuning gears ship with a template that you use to install them correctly. However, the word "template" appears nowhere, and to me, at least, it wasn't obvious.

The part of the box where the instructions are IS the template! You cut along the dotted line, punch out the small hole, and then use the flat edge (opposite where you cut) to line up against the edge of your neck's head.

Once I realized that, after searching the Web, it was easy.

Great Tuners

I've had several guitars and basses with Sperzels through the years, so when my old acoustic needed new tuners theses were an obvious choice for me. Easy install, solid tuning, quick string changes... What's not to love?

Very nice locking tuners

Tuners worked great. I would recommend buying the jig that is made to help position the pin hole. The paper jig that comes in the tuner package moved around too much to get a consistent hole drilled for all 6 tuners.

We're happy to hear you like the tuners. We agree, the tuner pin drill jig will make it much easier to align your drill for accurate mounting pin holes! Thanks for the feedback.

Just perfect ..

Hey man before these I had some bad grover tuners. Grover said it's the finest tuner we can buy .. Sperzel prove me the contrary .. My neck is quite flexible so very sensitive to my hand pressure when I play and before it never return to normal tuning there was always a string which was not correctly tuned. I simply didn't tune my guitar again with Spertzel. Moreover they're are so beautiful!

Sperzel tuners

Without a doubt, these are the best conventional locking tuners available. With zero string post wobble, they go a LONG way in keeping a non locking tremolo in tune. They are machined to very close tolerances. Still like to use a E/B string retainer though...:) with a tall spacer underneath
