Gotoh SG381 MGT Locking Tuning Keys — 3 a Side, 07 Button, XL Posts, Gold (SG381MGT-X-GOLD)
The Gotoh SG381 MGT (SG381MGT-X-GOLD) is a set of six locking tuning keys in a 3-a-side (3L, 3R) configuration with Gotoh 07 style buttons, XL long posts and gold finish. Built in Japan to Gotoh's precision engineering standards, the SG381 MGT features a 16:1 gear ratio, traditional thumbwheel Magnum Lock mechanism, non-staggered uniform 21.5mm posts accommodating headstock thickness up to 17mm, and a 10mm shaft hole requirement. Includes screw-in bushings, washers and fixing screws. Gold is the correct finish for instruments with gold hardware specification — Les Paul Standard, Custom and Traditional models with gold bridge, tailpiece and hardware, and any 3-a-side instrument where gold hardware continuity across the full instrument is a priority. The SG381 MGT is the 07 button variant in Gotoh's MGT locking range, offering a contemporary rounded button aesthetic with the same proven thumbwheel locking mechanism as the SG301 MGT. Before ordering, verify your headstock's existing bushing hole diameter (must be 10mm) and confirm base plate dimensions against the technical diagram provided.
Angkor Music — SG381 07 Button vs SG301 01 Button in Gold: Which Suits Your Instrument?
We stock both the SG381 MGT and SG301 MGT in gold finish, and the decision between them is purely about button style. Both use identical MGT thumbwheel locking, identical XL posts and the same 10mm bushing hole requirement. The SG381-X-GOLD uses the Gotoh 07 button — a contemporary rounded profile. The SG301-MGT-GOLD uses the Gotoh 01 button — a classic oval Rotomatic profile that closely matches the gold Grover 102 Rotomatics fitted as standard on Gibson Les Paul Standard, Custom and Traditional models. For players replacing factory gold Grover Rotomatics on a Les Paul who want the headstock to retain its original appearance, the SG301-MGT-GOLD's 01 button is the closer visual match. For players who prefer a modern rounded button on a gold hardware instrument — or who are fitting gold tuners to a non-Gibson instrument where the 01 button profile has no specific reference — the SG381-X-GOLD is the correct choice. Gold hardware on a premium instrument is a complete aesthetic statement, and maintaining finish continuity matters. Both are available at Angkor Music — contact us if you want to discuss button style options before ordering.
Finish Selection — SG381 MGT Range
| Finish | SKU | Best For |
|---|---|---|
| Gold | SG381MGT-X-GOLD (this product) | Gold hardware instruments — Les Paul Standard, Custom, Traditional |
| Chrome | SG381MGT-X-CHROME | Chrome or nickel hardware instruments |
| Pure Black | SG381MGT-X-BLACK | Black hardware instruments |
Gotoh 07 Button, MGT Locking and XL Posts
The Gotoh 07 button presents a contemporary rounded profile — a modern aesthetic on gold hardware instruments where a classic oval Rotomatic button is not the required visual reference. The MGT thumbwheel locking mechanism operates from the back of each tuner and is invisible from the front — wind the string normally, tune to pitch, tighten the thumbwheel to lock. XL posts at uniform 21.5mm height accommodate headstocks up to 17mm, covering the full range of 3-a-side headstock profiles including heavily lacquered and bound variants.
Who Is the SG381MGT-X-GOLD For?
- Players on gold hardware instruments wanting locking performance with a contemporary 07 button rather than the classic 01 Rotomatic profile
- Builders and luthiers fitting gold locking tuners to 3-a-side instruments with 10mm bushing holes and gold hardware specification
- Players on Les Paul or similar instruments with gold hardware who prefer the modern 07 button aesthetic over the vintage 01 button
- Players replacing factory gold Grover Rotomatics who want a visual change from the original Rotomatic profile — for those who want to retain the original look, the SG301-MGT-GOLD with 01 button is the closer match
- Players with chrome hardware should choose SG381MGT-X-CHROME — players with black hardware should choose SG381MGT-X-BLACK

Frequently Asked Questions
Should I choose the SG381-X-GOLD or the SG301-MGT-GOLD for my Les Paul?
If you are replacing factory gold Grover 102 Rotomatics and want the headstock to retain its original Rotomatic appearance, the SG301-MGT-GOLD with its classic 01 oval button is the closer visual match. If you prefer a modern rounded button or are fitting gold tuners to a non-Gibson instrument without a specific vintage button reference, the SG381-X-GOLD's contemporary 07 button is the correct choice. Both use the same MGT thumbwheel locking mechanism and XL posts.
How does the MGT thumbwheel locking work?
Wind the string normally, tune to pitch, tighten the thumbwheel on the back of the tuner to lock. Invisible from the front of the headstock. No change to stringing technique required.
Will these fit my guitar's existing 10mm bushing holes?
Yes — if your existing tuner bushings are 10mm diameter, the SG381 MGT installs directly. If a different bushing size is used, the holes require reaming by a guitar technician before installation. Contact us with your guitar's make and model for compatibility confirmation before ordering.
