Review: Great tuners - I bought these tuners for a dobro. They work great. They fit where the old tuners were with no modifications.. they were reasonably priced, shipped quickly, and a good value.. I would buy again!!! Review: Nice replacement for Martin tuners - I have a Martin DCME from the 80's where the tuners finally pooped out. I called Martin and they recommended these. I bought them and they fit perfectly. They're a little heavier than the original tuners, but I switched out the knobs for the originals which helped the weight and made it look stock. ## Features - Set of six enclosed, permanently lubricated guitar machine heads - 3 + 3 Configuration - 14:1 gear ratio - Nickel finish - Includes 5/8" washers, bushings and wood screws ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000EEMA6O | | Best Sellers Rank | #13,233 in Musical Instruments ( See Top 100 in Musical Instruments ) #50 in Electric Guitar Tuning Keys | | Color Name | Nickel | | Customer Reviews | 4.7 4.7 out of 5 stars (119) | | Date First Available | January 29, 2006 | | Is Discontinued By Manufacturer | No | | Item Weight | 10.4 ounces | | Item model number | 102N | | Material Type | Stainless Steel | | Number of Strings | 6 | | Product Dimensions | 9 x 4.8 x 1.8 inches | ## Images ![Grover Nickel Tuning Gear (102N) - Image 1](https://m.media-amazon.com/images/I/51FJrIKMwsL.jpg) ## Available Options This product comes in different **Style** options. ## Questions & Answers **Q: Are the Grover 102n tuners for Acoustic guitars or only for electric guitars??** A: I have them on an acoustic. They’re good for both. **Q: wiii these tuners drop in on a 75's martin d28 without any alteration?** A: Yes they should fit. The only question is the screw hole location of the existing tuner. These attached bottom center. **Q: Will they Fit Breedlove rainforest models?** A: These were exact replacements for my d28 Martin. Don’t know about Breedlove, but I copied this from their website Most of our current import models such as Organics, Discoveries, Pursuits, and Rainforests have a tuning ratio of 1:15 and have tuning machines with the same footprint as Gotoh SG510s and Gotoh SG381s. However, be sure to confirm that the screw placement is the same. For any other tuning machine information, please contact our customer service team. **Q: Will these fit an Epiphone sg?** A: These machine heads/ tuning gear are standard. They should fit fine unless it’s a vintage model guitar with different specs. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great tuners *by M***G on July 7, 2024* I bought these tuners for a dobro. They work great. They fit where the old tuners were with no modifications.. they were reasonably priced, shipped quickly, and a good value.. I would buy again!!! ### ⭐⭐⭐⭐⭐ Nice replacement for Martin tuners *by A***C on June 27, 2025* I have a Martin DCME from the 80's where the tuners finally pooped out. I called Martin and they recommended these. I bought them and they fit perfectly. They're a little heavier than the original tuners, but I switched out the knobs for the originals which helped the weight and made it look stock. ### ⭐⭐⭐⭐⭐ 1999 Taylor Guitar Machine Heads Exact Replacements *by P***T on February 5, 2023* So I accidentally dropped my 1999 Taylor 310 CE right on the D string tuner and it broke clean off. A little research and I found that Taylor used these exact machine heads on their guitars built in 1999. So found them here at Amazon at a reasonable price. Replaced all my machine heads and voila! Perfect match for the old worn out machine heads. Now my 1999 Taylor tunes much better than before without any slippage from the tuning mechanisms. Guitar holds tuning much better now. Amazing how much more authoritative these newer heads tune strings and keep them tuned. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/16407124-grover-nickel-tuning-gear-102n](https://www.desertcart.hr/products/16407124-grover-nickel-tuning-gear-102n) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-05-25*
