Lock Those Tuners Down!

Grover Rotomatic 406C6 locking guitar tuning machine heads give you easy tuning and positive string locking. With a gear ratio of 18:1, these locking tuners serve up all the goodness of standard Rotomatics - plus Grover's internal cam post. Stick the string through the string hole, hand pull to tension, and begin tuning. As you start to tune, only the locking cam inside the string post turns. The string post itself starts turning once the string is locked. In under one revolution of the string post, you'll be in tune - and you'll stay that way! Upgrade your axe with Grover's Rotomatic 406C6 locking guitar tuning machines.

Grover: top quality and a lifetime warranty
Grover's been keeping the world's finest string instruments in tune for more than a hundred years. It all started in the late 19th century with a few banjo and guitar tuning machine heads. From there Grover expanded into manufacturing tuners for ukulele, mandolin, dulcimer, violin, pedal steel, and eventually bass guitar. Did you know that the enclosed, permanently lubricated machine head was a Grover innovation? Today, Grover tuners are original equipment on many of the world's finest stringed instruments. Grover uses only the best materials and manufacturing methods, and they back their products with a wall-to-wall no-fault lifetime warranty.
