Gotoh SD90-MGT-SLB-B-3L/3R Black Guitar Tuning Machines
The Gotoh SD90-MGT-SLB-N-3L/3R Black Locking is a set of six vintage-style locking tuning machines built as a direct-fit upgrade for electric and acoustic guitars with smaller-bore headstocks. Each tuner uses Gotoh's MG-T traditional locking system with a knurled thumb screw on the back of the post, clamping the string at the nut so retuning after a string change is reduced to a single quick turn of the button.
- Configuration: 3 left / 3 right — fits standard 6-in-line or 3+3 headstock layouts.
- Gear Ratio: 1:15 — smooth, precise tuning adjustments.
- Bore: 8.8 mm — vintage-spec mounting hole, common on Gibson-style and many PRS SE guitars.
- Includes fastening screws and push-in sleeves for straightforward installation.
Locking Tuning Stability in a Vintage-Style Housing
The Gotoh SD90-MGT-SLB-N-3L/3R Black Locking set delivers modern locking tuning stability in a vintage-correct housing. Each machine head uses Gotoh's MG-T locking system with a knurled thumb screw on the back of the post, clamping strings firmly at the nut so they stay in tune through heavy bending and stage use. The 1:15 gear ratio gives smooth, precise adjustments, while the 8.8 mm bore matches vintage-spec headstock holes found on many Gibson-style and PRS SE guitars.
What to Check Before Buying
Confirm your guitar's tuner hole diameter first — the 8.8 mm bore fits vintage-spec instruments but may need adapter bushings for modern 10 mm holes. Fastening screws and push-in sleeves are included.
