Product Fundamentals
- Part of the Ratio Electric Series, this six-pack of 3x3 Graph Tech PRL-8311 machine heads features advanced Ratio Electric tech to ensure smooth, accurate and ultra-stable tuning. This patented system basically ensures that every tuner adjusts the pitch at the same rate, meaning that a half-turn raises or lowers the pitch of every string by around a semitone. These are also locking tuners, so after the string is threaded through, it&apos
- s locked in place by turning the thumb screw on the back of the machine head, and once you&apos
- ve given your strings a stretch, they can be tuned with surgical precision. The Graph Tech PRL-8311 tuners feature Contemporary Buttons and are easily mounted via a two-screw system, but can also be combined with one of the four included InvisoMatch mounting plates to adapt them for headstocks that are already set up for different screw systems.
