Detail 01
Metric sizing
Matches metric-spec guitars, typical of imports. An imperial-spec instrument needs a different TonePros set entirely.

ToneProsMetric Locking Tune-o-matic/Tailpiece Set (large posts) Chrome
Independent shopping perspective
The Korena take
Chrome locking Tune-o-matic bridge and tailpiece set, metric with large posts. For import Les Paul-style guitars where the bridge will not stay seated.
Strong match
Who this is for
- Frequent string changers tired of catching a loose bridge
- Import guitars with metric large posts needing chrome hardware
- Gigging players who want hardware that cannot shift mid-set
Consider the trade-offs
When to look elsewhere
- Guitars built to imperial hardware specs
- Anyone chasing a tone upgrade rather than mechanical stability
- Guitars with wraparound or non-Tune-o-matic bridges
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
.436 inch post diameter
Large-post version. Small-post guitars will not accept these studs, so measure before ordering.
Detail 03
.250 inch hole diameter
Your body's bushing holes must match this. A mismatch means drilling or plugging, which is luthier work.
Detail 04
2.913 inch hole-to-hole
Bridge post spacing. If your existing holes sit at a different distance, this set will not drop in.
Detail 05
Locking design
Set screws clamp bridge and tailpiece down, so neither lifts off when you take the strings off.
Detail 06
.545 inch bridge width
Front-to-back footprint of the bridge. Matters if a pickup ring or trim sits unusually close.
Final check
Know before you order
- 01Confirm post diameter, hole diameter and spacing on your guitar first — sizes are not universal
- 02Requires full string removal; have a new set ready
- 03Plan on redoing intonation and action afterward
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01How is this different from the gold version?
Finish only. Chrome and gold share the same metric large-post dimensions, so pick whichever matches the rest of your hardware.
02How do I know if I need metric or imperial?
Measure your bridge posts. These are .436 inch diameter with .250 inch body holes and 2.913 inch spacing. Anything else needs a different set.
03Do I need a tech to install it?
Not if your measurements match. It is a parts swap, though you will need to reset intonation and action after.
04Will it stop my bridge falling off during string changes?
Yes. That is what the locking set screws do — bridge and tailpiece stay clamped to the studs with the strings off.
