Detail 01
Auto-trim mechanism
The post cuts the string excess as you wind, so no tag ends sticking off the headstock.

D'AddarioAuto-Trim Tuning Machines/3 Per Side Chrome
1/4
Independent shopping perspective
The Korena take
A set of six self-trimming tuning machines in chrome, three per side, for headstocks with three tuners on each side. Cuts the string-winding step.
Strong match
Who this is for
- Players restringing often and tired of wire cutters
- 3x3 headstocks — Les Paul, SG, most acoustics
- Upgrading tuners that slip or feel gritty
Consider the trade-offs
When to look elsewhere
- 6-inline headstocks like a Strat or Tele
- Anyone wanting black, gold, or nickel hardware
- Players who need locking tuners for rapid changes
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
Only fits headstocks with three tuners each side. A 6-inline neck needs a different set.
Detail 03
Chrome finish
Matches chrome bridges and pickup covers. Against nickel hardware the brighter chrome reads slightly off.
Detail 04
Six-tuner set
Replaces the full set at once, so tuning feel stays consistent across all strings.
Detail 05
$99.99 for the set
Roughly the price band where tuners hold pitch reliably rather than needing constant retouching.
Final check
Know before you order
- 01Measure your existing tuner hole diameter — mismatched posts need bushings or reaming
- 02Screw holes may not line up with the old ones; you may drill new pilot holes
- 03Strings not included — have a fresh set ready for the install
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Will these fit my guitar?
They fit 3-per-side headstocks. Check your headstock hole diameter and mounting screw positions against your current tuners before ordering — vintage and import spacing varies.
02Do I still need wire cutters?
No, that's the point. The post trims the string as you tune up, so you skip the cutting step entirely.
03Are these locking tuners?
They're auto-trim tuners. The trimming happens as you wind — that's a different mechanism from a locking post that clamps the string.
04Can I install these myself?
It's a screwdriver job if the holes match. If the post diameter or screw pattern differs from your current tuners, it becomes a drilling job.
