This set of 3 x 3 right handed Graph Tech Ratio electric guitar tuners feature a different gear ratio on each tuner to provide consistent tuning across all strings. The thicker the core diameter of the string the more sensitive it is to tuning and so using a 12:1 ratio on the high e tuner and up to a 39:1 ratio on the low E (which is a thinner core but wound) ensures they feel the same to tune with one turn of any Ratio tuner changing the pitch by about one tone, this speeds up tuning and making it easy to reach the desired note. The double enveloping hardened steel gears mesh and turn smoothly and precisely and backlash is minimised. The locking system is operated by a thumb screw on the back of the tuner for quick and easy string changes. The tuners have two mounting pins which fit in to holes in the back of the headstock to stop the tuner rotating and the Ratio tuners include Graph Tech's InvisoMatch mounting plates which adapt all common screw placements to the two pin tuner (mount the plate to the headstock, then mount the tuner to the plate) meaning these tuners can be installed on most guitars with no modification. The InvisoMatch mounting plates included adapt the following screw styles: Kluson Deluxe 2 screw, 45 degree screw (common on Ibanez, Schecter, ESP, Jackson and PRS SE guitars), in line centre screw (common on Gibson Les Paul style guitars) and 70's Fender style 2 screw (not modern Fender 2 pin tuners).
Please note while these are a 3 x 3 set, they will only fit right handed guitars due to each specific tuner needing to be in the correct order (if used on a left handed guitar the custom ratios would be reversed and not work as designed).

Brilliant Replacement Locking Tuner’s for an Gibson SG
Brilliant service from GTM….. fast delivery and the Graphtech were much better than the Gotoh I had initially used to replace the originals. Very happy and considering using same brand on my J45 acoustic. The interchangeable fitting plates that enable you to match most screw fixings on the headstock are are great idea, a bit like the Hipshot plate but tidier.

Great set of tuners, easy to install
I needed a new set of tuners to replace some less than idea gotoh's on my Edwards LPC.
I found these easy to install thanks to the plates (the screws they come with were too small for the pre-drilled holes, but held it enough to get the top screwed in)
The guitar now is more more stable in holding tune (although it's still a LP so not 100%) and tuning is easy thanks to the ratio system.
Speedy service from GTM, would defo use again.
