The PRL-8731 are a right-handed set of Locking RATIO® Calibrated Machine Heads for electric guitars that use 6-in-line tuners. This set has oval style knobs.

The tuners have a two pin casing that can be used as is, or with our Patented InvisoMatch Mounting Plates. 4 different sets of InvisoMatch mounting plates in brushed aluminum are included to make installation on most guitars fast and accurate by using your existing screw mounting holes.

RATIO® is Graphtech’s patented gear technology. RATIO® Calibrated Machine Heads incorporate different string gauges into the tuning equation.

  • From Low E to High E 39:1, 24:1, 20:1, 35:1, 20:1, 12:1.

Graphtech balanced the gear ratios to each string simplifying the tuning process. With RATIO®, a half turn is a semitone. Every string reacts the same to any tuning adjustment. Predictable, precise tuning, on every string.
