The Grover Sta-Tite 18:1 Vertical 97 Series Machinehead Set 3 + 3 Nickel - Acrylic Buttons brings the timeless, open-gear aesthetic of early 20th-century guitars into the modern era.
High-Ratio Precision & Classic Detail
While these tuners feature the iconic "butter bean" buttons and a traditional nickel finish that looks right at home on vintage-style acoustics and solid-body electrics, they have been significantly upgraded under the hood.
Designed for solid headstocks, these vertical-mount machine heads offer a professional level of precision that far exceeds the performance of the original parts they emulate.
The standout improvement in the 97 Series is the jump to an 18:1 gear ratio.
This higher gearing provides a much finer degree of control than standard open-gear tuners, allowing you to dial in your tuning with incremental accuracy.
Despite the modern performance, the visual details remain authentic, featuring the classic butter bean shape in a lightweight acrylic.
The open-gear construction not only looks elegant but also keeps the overall weight of the set down to 6oz, which helps prevent headstocks from feeling heavy or unbalanced.
Quality Construction for Solid Headstocks
Built specifically for vertical installation on solid headstocks, these tuners are engineered for stability.
The gear and worm are precision-cut for a smooth, consistent feel, ensuring that your tuning remains stable even during heavy playing.
The set is finished in a warm nickel that develops a beautiful character over time, unlike high-polish chrome.
Each set comes complete with all the necessary vintage-style bushings and wood screws for a clean and professional-looking installation.
