Weekend Mod Project: D-28 Open-Gear Tuner Upgrade

I’ve made an effort to play more acoustic guitar in 2014, which has partly entailed overhauling my Martin D-28. Now a decade old, the spruce and rosewood dreadnought has matured both acoustically and aesthetically; it has also endured some normal wear and tear. Several months ago, I performed overdue maintenance on a worn mammoth ivory saddle. More recently, I set out to replace the stock Gotoh tuners (right) — at least one of which was showing symptoms of a stripped gear. The Martin-labeled enclosed machines are unfortunately not available through retailers (either singly or as a set), which means owners must navigate the myriad aftermarket options.

A generic, Gotoh labeled drop-in replacement is available, but for several years I had been eyeing vintage-inspired, open-gear tuners. Open-gear tuners are stock on most high-end Martin vintage reproductions, and boutique manufacturers like Collings and Bourgeois also opt for the classic look. The problem is that open-gear tuners have a very different overall design footprint (including set screws and and peghead bushings) than most enclosed tuners — which is to say this is no trivial mod.

After extensive research, I opted for a well-reviewed and reasonably priced set of Gotoh open-gear tuners available from Luthiers Mercantile International. Acoustic Guitar and Martin Guitar Forum users routinely compare these favorably to pricier, American-made models by Waverly. Installation can be daunting for the uninitiated, especially if it entails drilling and reaming holes in an expensive instrument. Needless to say, it’s a job worth taking to your luthier if you feel the least bit uncomfortable with the mod. For those who take the DIY route, I hope this post can serve as a helpful guide (this page and this page are also extremely helpful).

Weekend Mod Project: Frequent Flyer-caster, Part 3

Now we come to the end of my travel Tele odyssey. In Part 2, I provided an overview of the the mods I envisioned for this guitar, including crucial changes to the electronics, bridge, and general look of the instrument. The electronics and hardware were fairly simple changes, given my past experience working on guitars. However, the cosmetic changes — including a vintage-tinted neck and body finish “relicing” — were new territory for me as an amateur luthier.
