This set of 3 x 3 Gotoh SG381 locking tuners feature a 1:16 gear ratio for tuning up quickly and accurately. Gotoh's Magnum Locking system is operated by a traditional thumb screw on the back of the tuner for quick and easy string changes. The 'Rock-Solid' string post improves the tuning stability of the tuner and stays strong during bending and tremolo use, special elastic parts eliminate any rattle in the post and transmission of string vibration to the instrument is maximised. The tuners are completely sealed and permanently lubricated through Gotoh's 'Lubri-Coat' technology, a coating applied to the worm gear to ensure better contact between the worm and spur gear wheel, backlash is minimised and durability is increased. The 3 x 3 set has the screw attachment holes offset at a 45 degree angle to the tuner post, this set up is common on a lot of 3 x 3 headstock designs from Ibanez, Schecter, ESP, Jackson and PRS SE guitars.

We have spec'd these tuners with Gotoh's extra long string posts, they are 21.5 mm (0.85") from the base of the tuner (where the tuner rests against the back of the headstock) to the string hole for use with headstocks that are thicker than, or for reducing the break angle of the string over the nut if required.

The button shapes available are as follows:

  • 01 - This is a modern shape button for 3 x 3 headstocks
  • 04 - This is a keystone/tulip shape button

First Class Quality Product & Service

I purchased a couple of sets of these to fit to my 12 string acoustic guitar. Fitted exactly with no alterations required to my guitar , plus the quality , smoothness of use is superb. Makes changing strings far quicker and easier now ... and with 12 strings , this is a massive bonus :-)
