D'AddarioAuto-Trim Tuning Machines/3 Per Side Gold
1/2
Independent shopping perspective
The Korena take
Locking tuning machines with a self-trimming design, three per side, in gold. For anyone restringing a six-in-line-free guitar who wants faster string changes and better tuning stability.
Strong match
Who this is for
- Players who restring often and want no string wind or excess to snip
- Set-neck guitars with three-a-side headstocks needing tuning stability upgrades
- Matching gold hardware on a guitar that already has gold appointments
Consider the trade-offs
When to look elsewhere
- Six-in-line headstocks like Strats and Teles — wrong configuration
- Players unwilling to check headstock hole size and screw placement first
- Anyone who wants vintage-correct open-gear looks on a period build
What matters in use
The specifications, translated
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.
Detail 02
3 per side layout
Fits Les Paul, SG, and similar headstocks. Six-in-line guitars need a different set.
Detail 03
Locking mechanism
String is held rather than wound, so it settles faster and slips less after bends.
Detail 04
Gold finish
Gold plating wears with hand and arm contact faster than chrome or nickel, especially near the bridge side.
Final check
Know before you order
- 01Measure your existing headstock holes and post spacing before ordering
- 02Strings and any bushings or conversion adapters are separate
- 03Screw holes may not line up with existing ones on your headstock
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Will these fit my Les Paul?
The 3-per-side layout matches Les Paul style headstocks, but check your headstock hole diameter and mounting screw positions before installing. Not every 3-a-side guitar uses identical spacing.
02Do I still need to wind the string?
No. The string is locked in place and trimmed as you tune, which is the point of the auto-trim design.
03Will these keep my guitar in tune better?
Locking tuners eliminate slip from loose string windings. They do not fix tuning problems caused by the nut, bridge, or bad strings.
04Can I install these myself?
It is a screwdriver job if the holes match. If they do not, you are drilling into your headstock — worth handing to a tech.
