Featuring a precise 16:1 gear ratio, Rock-Solid string posts, and dual post heights, these tuners are designed for players who demand reliability and style, especially on non-locking tremolo guitars and heavy string-benders. The durable Lubri-Coat™ polymer finish ensures long-lasting smooth operation, while the sleek Cosmo Black finish adds a modern edge to your instrument. ## Description Traditional thumbscrew-style locking functionality with Gotoh technology.Pull the string taught through the tuner hole, and with a twist of the thumbwheel the string is locked into the post. Just a few turns of the tuner knob and you're up to pitch. Since there's just a partial wrap of string around the post, tuning stability is dramatically improved. Locking tuners are excellent for non-locking tremolo guitars, and for players that do heavy string-bending.Rock Solid™ string posts eliminate looseness and reduce backlash for improved tuning stability. No more wobbly string posts to cause tuning problems. Two post heights eliminate the need for string trees.The Lubri-Coat™ process electro-coats the gears with a special polymer layer. This eliminates the need for oil and keeps the lubrication where it's needed, for the life of the tuner.Gotoh SG381 MG-T16:1 ratio10mm (13/32") diameter pegholes required2 post heights: 18.5mm and 20mmRemovable metal knobsCosmo Black* finishThreaded hex bushings and mounting screws (6 each) includedSet of 6 in-line tuners*These tuners are available with Gotoh's translucent Cosmo black finish, a popular new alternative to standard solid-black plating. Review: Fits and feels perfect - Bought a cheap made in China Jackson to modify for playing thrash metal, and the tuners were the first step. Had more trouble taking the old tuners out than anything. Once the old tuners were removed it took maybe 10 minutes to install these guys - no drilling or reaming necessary. Look great, feel great, and keeps everything in tune where you want it to be. Review: Gotoh quality with a simpler more intuitive lock than the MAG style - Exactly as expected...they are Gotoh locking tuners. Easy swap, well constructed, and function perfectly. Locking tuners aren't intended to enhance tuning stability, but the make string changes quick and easy. These are screw locking with a central post, not the Mag lock style, so they are less expensive than the common Gotoh lock style. They make an excellent upgrade for an Ibanez RG or S series in the middle of their price range. You will have to drill pilot holes for the tiny screw on the back, as these don't have the locking nubs the stock tuners use, so you will alter your headstock unless you are replacing screw in tuners to start with. ## Features - Traditional thumbscrew-style locking functionality with Gotoh technology - Locking tuners are excellent for non-locking tremolo guitars, and for players that do heavy string-bending - Rock-Solid string posts eliminate looseness, for improved tuning stability, and two post heights eliminate the need for string trees - 16:1 gear ratio for precise tuning - Set of 6-inline tuners comes with mounting hardware (6 bushings, washers, and screws) ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B077K9CYLW | | Color Name | Cosmo Black | | Customer Reviews | 4.8 4.8 out of 5 stars (150) | | Date First Available | 11 August 2018 | | Item Weight | 50 g | | Item model number | #AN7105-CB | | Material Type | Metal | | Number of Strings | 6 | | Product Dimensions | 15.19 x 6.1 x 4.39 cm; 50 g | ## Images ![Magnum Lock-Trad 6-In-Line Guitar Tuners, Cosmo Black - Image 1](https://m.media-amazon.com/images/I/61kYyQ96VxL.jpg) ## Questions & Answers **Q: Will this fit on a Jackson JS12?** A: Yes they will fit, I looked at the Js12 Dinky. Remember three of the tuners in this set, have shorter posts, so you can remove 2 string trees. I used them and they work and look great. If you want the ones that are all equal length, check with the supplier, to make sure of which set to get. They are knowledgeable and friendly. **Q: Fit fender strat** A: The fit will depend upon the type of tuning pegs your guitar has. Reach out to Stew-Mac. They are very helpful. **Q: Will these fit a jackson js32 rhoads left handed ?** A: No not unless the guitar has a reverse headstock. These are for a standard right-handed guitar. **Q: Will they fit on the Squier strat mini guitar?** A: Please just check the back of the headstock of your guitar. If the current tuners have no screws you will need to drill holes for screws when you fit these tuners. If the current tuners have the screw on 45-degrees like these they'll fit straight on. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Fits and feels perfect *by K***R on 30 August 2023* Bought a cheap made in China Jackson to modify for playing thrash metal, and the tuners were the first step.

Das war bei meiner Ltd Ex400 überhaupt nicht der Fall. Und nach einem Jahr im Gebrauch frag ich mich, warum ich nicht schon viel früher gewechselt habe. Das Wechseln der Saiten ist deutlich einfach. Am Kopf einfädeln, stramm ziehen, mit der Rändelschraube festdrehen, überschüssigen Saitenrest abpitschen. Fertig. Und stimmstabiler als herkömmliche Tuner sind sie auserdem. Eine Investition, die sich lohnt. ## Frequently Bought Together - Gotoh Magnum Lock-Trad 6-In-Line Guitar Tuners, Cosmo Black - XIYANGJUAN 4Pcs Metal Guitar Knobs Black Volume Tone Speed Control Knob Dome Knobs with Allen Keys Screws for Fender Telecaster Gibson Les Paul Electric Guitar Bass (Black) --- ## 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/318223883-magnum-lock-trad-6-in-line-guitar-tuners-cosmo-black](https://www.desertcart.hr/products/318223883-magnum-lock-trad-6-in-line-guitar-tuners-cosmo-black) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-11-11*
