Graph Tech Ratio 6-In-Line Electric Locking Machine Heads - Chrome Contemporary Mini - Open-Box

Open-box but never used. Comes with all hardware and original packaging.

RATIO® 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.

We balanced the gear ratios to each string simplifying the tuning process.

With RATIO®, a half-turn is a semi-tone!

Every string reacts the same to any tuning adjustment. Predictable, precise tuning, on every string.

The PRL-9721 and PRL-9731 are right-handed sets of Locking RATIO® Calibrated Machine Heads for electric guitars that use 6-in-line tuners with staggered posts (eliminates the need for a string tree).
