Graph Tech Ratio Locking Guitar Tuners (6 In Line)

With different gear ratios on each string to account for how different gauges are wound, Graph Tech Ratio tuners give you a consistent tuning experience.

Ratio Tuned Machine Heads are the first and only machine head to incorporate the different string gauges into the tuning equation. The gear ratios range from 12:1 to 39:1, specific to the relative core size of the string being spun on each, resulting in a consistent response across all strings. One half turn is a semi-tone; one turn is a tone.

Installation is unprecedentedly simple, as each set of Ratios comes with four full sets of Invisomatch mounting plates. In most cases, whatever the current hole profile under the old tuners - one or two screws, 45 degree, 90 degree, etc - one need only position the appropriate plate between the tuner and headstock, utilizing the existing screw holes with no drilling or filling required.

The PRL-8721-C0 is a set of Ratio Locking Tuned Machine Heads for an electric guitar that uses six in line tuners. It has a contemporary mini shaped button, has a two pin casing and is finished in chrome.

Includes InvisoMatch Standard Mounting Plates for easy installation. Fits most headstocks.

"Rock Solid Precision Tuning"

I bought a set of these locking tuners to upgrade a cheap strat copy guitar that I own that had low cost non-precision tuners. The difference between the old tuners and these new Graph Tech tuners is like night and day! Now, not only is it easy to tune each string quickly and precisely, but my guitar's tuning stays rock solid with each string locked in place with no string wind to stretch out. They were easy to install by the instructions and the included InvisoMatch mounting plates. Fortunately, I didn't have to enlarge the tuner holes in the headstock of my guitar with a drill or router; they were just the right size. Also, I think these tuners are very aesthetically pleasing and don't look awkward on the headstock. I'm extremely satisfied with this purchase.
