D'AddarioAuto-Trim Tuning Machines 6 In-Line Black
Independent shopping perspective
The Korena take
A six-piece in-line tuner set with a built-in string trimmer, for players replacing tuners on a one-sided headstock like a Strat or Tele.
Strong match
Who this is for
- Players who restring often and hate reaching for wire cutters
- Replacing worn or slipping tuners on a six-in-line headstock
- Cleaning up hardware to all-black on a dark guitar
Consider the trade-offs
When to look elsewhere
- Guitars with 3+3 headstocks — these will not fit
- Players wanting to swap a single tuner; this is a full set
- Anyone unwilling to check hole size and screw pattern first
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
Auto-trim
The post cuts the excess string as you tune up, so no dangling ends and no wire cutters.
Detail 03
Set of six
Replaces every tuner on the guitar at once. Mixing with old tuners defeats the point.
Detail 04
Black finish
Matches black hardware. Next to chrome or gold bridges and jack plates it will look deliberate or off, depending on the guitar.
Detail 05
$129.99
Tuner-set money, not budget-part money. Worth it if you change strings weekly, less so once a year.
Final check
Know before you order
- 01Measure your headstock post holes and screw placement before ordering — fitment varies by guitar
- 02Nothing but the tuners; strings, bushings and tools are separate
- 03Older or drilled headstocks may need plugging and redrilling to line up
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Will these fit my Les Paul?
No. These are six-in-line, meaning all six tuners sit on one side of the headstock. A Les Paul uses a 3+3 arrangement and needs a different set.
02What does auto-trim actually do?
The tuning post cuts the excess string as you bring it up to pitch, so you finish a restring without wire cutters and without sharp ends sticking out.
03Do I need a tech to install these?
Not necessarily, but you should confirm the post holes and screw pattern match your headstock first. If they don't, the job becomes drilling work best left to a tech.
04Is this one tuner or the whole set?
The whole set — six tuners covering an entire in-line headstock.
