Proline3+3 Diagonal Mount Tuning Machines Chrome
1/3
Independent shopping perspective
The Korena take
A six-in-line-alternative set of 3-per-side tuning machines with diagonal mounting screws, in chrome. For repairing or upgrading a three-a-side headstock.
Strong match
Who this is for
- Replacing worn tuners on a Les Paul or SG-style headstock
- Completing a three-a-side build that shipped without hardware
- Fixing a guitar that drifts sharp or flat between songs
Consider the trade-offs
When to look elsewhere
- Strat, Tele, or any six-in-line headstock
- Bass players — bass posts and holes are considerably larger
- Anyone unwilling to check existing screw holes and post diameter
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
Diagonal mount
The mounting screw sits at an angle rather than straight behind the post. Existing holes must line up or you will drill new ones.
Detail 03
Chrome finish
Matches chrome bridges and hardware. Nickel hardware reads warmer and slightly duller, so a mixed headstock will look off.
Detail 04
Complete six-tuner set
Whole headstock at once. Replacing a single failed tuner from a set this way leaves five spares.
Final check
Know before you order
- 01Measure your headstock post holes — bushing diameter varies between makers
- 02Mounting screw positions may not match existing holes; plugging and redrilling is common
- 03Restringing and a fresh setup are needed after the swap
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Will these drop into my Les Paul-style guitar?
The 3+3 layout matches, but post hole diameter and the diagonal screw position vary. Measure your current tuners and holes before committing.
02What does diagonal mount mean?
The single mounting screw enters the headstock at an angle off the post centerline, rather than directly behind it. It is a specific hole pattern to match.
03Can I use these on a six-in-line headstock?
No. This set is mirrored three-per-side. A Strat or Tele headstock needs six tuners all facing the same direction.
04Will new tuners fix my tuning problems?
Only if the tuners are the cause. Slipping gears and loose posts, yes. Binding at the nut or a badly stretched string, no — those need separate attention.
