Original Grover Rotomatics!

Grover Rotomatic 102N guitar tuning machine heads are a marvel of engineering and design. Rotomatics have a gear ratio of 14:1, and a housing that provides optimal bearing for worm, gear and string post. Precision-cut worm and gear serve up perfect meshing, eliminating backlash and slippage. A countersunk tension screw lets you customize tension to your personal preference. The Rotomatic's gear box is permanently lubricated, giving you a lifetime of trouble-free operation. 5/8" washers, bushings and wood screws are included with this set of six Grover Rotomatic 102N guitar tuning machine heads.

Great tuners

I've put these same tuning machines on several of my guitars now. They work smooth and stay in tune. I can pick a guitar up off the rack after weeks of it sitting there and it will still be in tune.

Can't Beat Perfect!

I have several sets of Grover tuners on my guitars, both acoustic and electric; I have NEVER been disappointed with the quality or reliability of these tuners.

Down here in Texas, we have many expressions. One is,"If it ain't broke, don't fix it." Grover hasn't seen a need to change or modify the Rotomatic line of machine tuners.

Tuners

Michael was the best. Gave him the model and serial number of my Takanimi and he matched it with a set of grover tuners.

Great for Martin road series

Installed these on my Martin D11e to replace factory tuners. The ones that shipped with the guitar weren't horrible, just sometimes I would have to turn several times for a string to tune up and then it would be more than my intended adjustment. Happy with my purchase and the installation was easy.

Great Replacement Tuners

These tuners were purchased for a brand new guitar. While changing the strings on a less than week old guitar, the A tuner broke apart. I contacted the manufacturer and in all fairness they sent me a new set. However, now I was dubious of the rest of the tuners possibly breaking during a performance. Grover tuners have been around for ages and used on many guitars today. The set I bought fit exactly, worked perfectly and were reasonably priced. The internet tells you they are made in China but in reality they are manufactured in Taiwan. I strongly recommend these if you are considering upgrading your guitar.
