Independent shopping perspective
The Korena take
The PRL-8731-B0 is a black set of Graph Tech Ratio locking machine heads for electric guitars with six tuners in a line. It combines a classic-shaped button with a two-pin casing and includes InvisoMatch Standard Mounting Plates to support installation. Its fit is defined first by the six-in-line layout, so treat this as a replacement set for guitars built around that headstock arrangement rather than a 3+3 configuration.

Who this is for
