PRS Phase III Vintage Style Locking Tuners – Nickel with Cream Button (Set of 6) | No Limit Guitar Co, Idaho Falls

Important compatibility note: Phase III tuners are NOT a direct replacement for Phase I or Phase II tuners — modifications to the existing headstock will be required for those models. This set is designed for Core, S2, and SE Series McCarty models, and does NOT fit Core models manufactured prior to 2020. Please confirm compatibility with your specific guitar before ordering.

This set of six PRS Phase III Vintage Style Locking Tuners in nickel with cream buttons brings PRS's most refined locking tuner design — engineered specifically to preserve, rather than drain, the tonal energy of the guitar's woods while delivering reliable locking stability and a highly usable gear ratio. Designed for Core, S2, and SE Series McCarty models, this open-back vintage-style tuner set includes all the hardware needed for a complete installation: six locking thumbscrews, six grommets, and twelve mounting screws. For McCarty model owners who want genuine PRS tuning hardware engineered with tone preservation as a primary design goal, this set delivers both function and a handsome, vintage-correct appearance.

Product Overview

Every component a guitar string physically touches has a measurable effect on the instrument's tone and sustain — and tuning pegs are among the few parts of a guitar in direct, constant contact with the string at all times. PRS's design philosophy behind the Phase III machine head reflects this directly: the engineering goal was twofold — first, that the tuner itself doesn't detract from the natural tonal contribution of the neck and body tonewoods, allowing them to do the musical work they're built for, and second, that the tuner maintains excellent tuning stability while offering a genuinely useful gear ratio for practical, everyday tuning.

This particular vintage-style variant brings an open-back tuner design to the Phase III locking platform — a design choice grounded in long-established acoustic guitar and bass history, where open-back tuners have proven their reliability and durability across generations of high-quality instruments. Concerns about open-back designs being more susceptible to dirt or premature wear don't hold up against this history; open-back tuners have a long track record of dependable performance when properly engineered, and PRS's Phase III vintage-style tuners carry that design tradition forward with modern locking functionality built in.

The cream button paired with a nickel finish gives this tuner set a distinctly vintage-inspired visual character that suits PRS's McCarty model line particularly well — the McCarty series itself draws heavily on vintage-inspired design cues, and these tuners are a cohesive aesthetic match. The complete hardware package — six locking thumbscrews, six grommets, and twelve mounting screws — provides everything needed for a full installation without sourcing additional parts separately.

Compatibility requires careful attention with this tuner set. It is specifically designed for Core, S2, and SE Series McCarty models, and does not fit Core models manufactured prior to 2020 — a meaningful cutoff that reflects a headstock or mounting specification change at that point in PRS's manufacturing history. Equally important, Phase III tuners are not a direct replacement for guitars originally equipped with Phase I or Phase II tuners; modification to the existing headstock would be required to install Phase III tuners on a guitar that didn't ship with them originally. Players should confirm their model and production year fall within the compatible range before ordering.
