Description
Part of Allparts' Top Tier™ line — tuning keys engineered to bring genuinely professional-grade performance within reach of players and builders at every level, not just top-tier custom shops. Where Allparts' companion Top Lock™ line adds a locking mechanism for players who want tool-free, lock-solid string changes, Top Tier is built for players who want that same silky-smooth feel and impeccable tuning stability in a traditional non-locking format — precision-engineered rather than adapted from a generic off-the-shelf spec.
This specific model — the Mid-Size 6-In-Line — is Top Tier's answer for smaller headstocks. Rather than simply shrinking a full-size tuner down, Allparts built the housing genuinely compact from the ground up, so a guitar with limited headstock real estate doesn't end up feeling neck-heavy the way a full-size tuner set can cause. It's positioned as the sleek, contemporary counterpart to Top Tier's more traditionally-styled Vintage and Vin-Mod tuner families — same underlying engineering standard, aimed at a more modern-looking build.
What actually makes these "Top Tier" rather than a basic replacement tuner:
- Staggered posts — E, A, and D posts sit at a different height than G, B, and high E, giving every string its correct break angle off the nut without needing a separate string tree. Fewer parts, cleaner headstock, one less thing that can fail.
- Internal tension washer — fitted at the base of the string post specifically to eliminate "post wiggle," the small amount of play that robs sustain and subtly undermines tuning stability over time on cheaper tuners.
- Nylon washer on the gear shaft — gives the tuning action itself a noticeably smoother, more precise feel under the fingers, rather than the gritty resistance you get from a bare metal-on-metal gear shaft.
- Sealed, die-cast zinc housing — fully encloses the internal gearing, keeping out moisture, hand sweat, and general grime that would otherwise corrode an open-back tuner's mechanism over years of use.
Fitment note: requires 10mm tuning key holes.
