Independent shopping perspective
The Korena take
Graph Tech’s PRT-952-201 is a six-piece set of Ratio InvisoMatch Premium Installation Plates for fitting Ratio Tuned Machine Heads. Select the plate that matches your guitar’s current machine-head screw position, then use the existing mounting holes for the installation. The set uses a modern Fender-style two-pin mounting system; its two-pin mount is slightly larger than the Ratio two-pin mount. It is a hardware-matching solution for an existing headstock layout, rather than a universal tuner claim.
Strong match
Who this is for
- Installing Ratio Tuned Machine Heads while retaining a guitar’s existing mounting-hole layout.
- Guitars with current machine-head screw positions that match an InvisoMatch plate.
Consider the trade-offs
When to look elsewhere
