Grover Machine-Heads


For almost a century, we’ve been keeping the world’s finest string instruments in tune. It started in the late 1800’s when Grover first produced a few guitar and banjo machine heads, then expanded into additional production of tuners for bass guitar, pedal steel, mandolin, dulcimer, ukulele and violin.

While many changes have taken place over the years, the one constant has been that we continue to supply the music industry with the finest products available. From the world’s first enclosed, permanently lubricated machine heads, to our newest technological breakthroughs, the one-step self lock, we are proud to be original equipment on many of the world’s finest string instruments.

Since our production process utilises only the top of the line quality standards, we proudly stand behind our machine heads with the following lifetime warranty... should your Grover tuners ever fail, for any reason, simply return them to us for a fast and friendly no charge repair or replacement. If you are already using Grover products, thank you for your support in making Grover the most trusted name in music around the world.

If not, maybe it’s time to “Change Over to Grover!”


POST HOLE SIZES

Many of the Grover tuners will fit the existing holes in the headstock without any modification at all.

However, we realize sometimes the existing holes need to be enlarged a bit in order for our tuners to fit properly.

As a result, we have provided the chart below showing the exact drill bit needed for each tuner series.

Please note, always enlarge the hole size from the front, or face, of the headstock.

ORIGINAL LOCKING ROTOMATCS® (106 SERIES)

US PATENT NUMBER 6,078,001 Grover’s patented locking tuners have eliminated the obstacles of other locking devices. Since there are no external mechanisms to initiate the locking action, the machine head’s appearance is like any other. The entire locking mechanism is self-contained and self-actuated.


The introduction of the new Grover Locking Rotomatics® gives you the ease of use provided by a standard tuner and the positive locking of our internal cam post. Simply insert the string through the string hole, pull to tension by hand and begin tuning. As you start to tune, only the locking cam in the string post turns. Once the string is locked, the string post begins to turn allowing you to bring the string to pitch. In less than one revolution of the string post, you will be in tune, to stay in tune. Gear ratio is 18 to 1. Available in chrome and gold For standard guitars, set of 6 (3+3)
