This set of 6 in line right handed Graph Tech Ratio locking 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 and the tuners have staggered string posts to provide the correct string tension over the nut and eliminate the need for string trees, improving tuning stability, the EA strings have 21 mm tall posts, the DG strings have 20 mm tall posts and the Be strings have 19 mm posts.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/Ltd and Jackson guitars), centre screw (common on Gibson Les Paul style guitars) and 70's Fender style 2 screw (not modern Fender 2 pin tuners). The plates are reversible so can be used for both right and left handed 6 in line headstocks.

As standard these do not fit Fender guitars with their 2 pin mounting tuners, to covert this style you will also need the Graph Tech Fender 2 Pin InvisoMatch plates (product code: PRT-952-201-C0) that we stock as a separate item.
