Overview

Locking Ratio calibrated machine heads for electric guitars that use 4 x 3 tuner configuration.

The Graph Tech 7-string Ratio 4+3 electric guitar locking machine heads incorporate different string gauges into the tuning equation. Graph Tech 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 adjustments, delivering predictable, precise tuning on every string. The Graph Tech PRL-8521 is a right-handed set of locking Ratio calibrated machine heads for electric guitars that use 4 x 3 tuner configuration. It fits many Gibson, Epiphone and PRS-style guitars, and any other guitar with a 4+3 headstock.

It has a two-pin casing that can be used as is, or with Graph Tech’s InvisoMatch mounting plates. Four 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.

Features

Includes:
7 machine heads, mounting screws, and bushings
4 complimentary sets of aluminum mounting plates
