Important compatibility note: Phase III tuners will NOT retrofit to any PRS model without modification, except models that already have Phase III tuners installed (Private Stock and Core Series Electrics, 2011–Present). Please confirm compatibility with your specific guitar before ordering.
This set of six PRS Phase III Worm Collar Locking Tuners in gold features an unplated brass shaft and represents the precision tuning hardware found on PRS Private Stock and Core Series Electric guitars from 2011 to present. The set includes bushings and installation screws for a complete, ready-to-install package on compatible models. For owners of Private Stock and Core Series PRS electrics who need genuine factory replacement tuners, this set delivers authentic PRS Phase III specification and finish.
Product OverviewThe Phase III worm collar locking tuner design represents one of PRS's more advanced and precisely engineered tuning machine systems, used specifically on the brand's Private Stock and Core Series Electric models since 2011. The worm collar locking mechanism provides secure, reliable string locking at the tuning post, contributing to the tuning stability and precision that PRS's higher-tier electric guitars are known for. Unlike standard locking tuners that may be designed for broader cross-model compatibility, the Phase III system is engineered as an integrated part of the specific headstock and tuner mounting configuration found on these particular PRS model lines.
The unplated brass shaft is a notable material specification — brass offers a particular density and resonant character that some builders and players associate with subtle tonal benefits at the headstock, in addition to being a durable, long-wearing material for the mechanical demands of a tuning machine shaft. The gold finish matches the cosmetic appointments commonly found on PRS's higher-end Private Stock and Core Series instruments, ensuring a visually cohesive replacement rather than a mismatched aftermarket part.
It's critical to understand the compatibility limitation before purchasing this set: Phase III tuners are not a universal drop-in replacement for PRS guitars broadly. They are specifically designed for the headstock and mounting configuration used on Private Stock and Core Series Electrics built from 2011 onward, and they will not retrofit to other PRS models — including SE models or older Core Series instruments — without modification to the headstock. This set is intended for replacement on guitars that already have Phase III tuners installed from the factory, not as an upgrade path for guitars with a different tuner system.
