Detail 01
Roller nut
Each string sits on a small bearing that turns as the string moves, so it slides instead of catching in a slot.

FenderLSR Roller Nut
1/2
Independent shopping perspective
The Korena take
Roller nut that replaces a standard nut with bearings under each string. For players who bend hard or use a trem and fight tuning slip.
Strong match
Who this is for
- Guitars with a tremolo that go sharp or flat after dives
- Heavy benders whose strings bind and ping in the nut slots
- Players adding stability without going to a locking nut
Consider the trade-offs
When to look elsewhere
- Players happy with tuning stability on a fixed-bridge guitar
- Anyone wanting a drop-in swap — this needs routing on most necks
- Players who want the traditional look of a bone or synthetic nut
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
LSR design
Fender's low-friction roller nut, used on their deluxe and American models with tremolos.
Detail 03
Not a locking nut
Strings still pass over freely, so you keep normal headstock tuner adjustment — no allen key at the nut.
Detail 04
String spacing is fixed
The bearing positions set spacing. It has to match your bridge spacing or strings sit off-center over the pickups.
Final check
Know before you order
- 01Most necks need routing to accept it — plan on a tech unless you've done nut work
- 02String gauge range is limited by the bearing slots; very heavy gauges may not fit
- 03Won't fix tuning problems caused by worn tuners or a poorly cut bridge
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Does a roller nut fix tremolo tuning problems?
It fixes the part caused by strings binding in the nut. Tuner slip, bridge friction and old strings still need addressing separately.
02Is this a drop-in replacement?
Rarely. Most necks need to be routed for the LSR's footprint. Guitars that shipped with one will swap directly.
03Roller nut or locking nut?
A locking nut clamps strings and needs fine tuners at the bridge. A roller nut keeps normal tuners and standard restringing.
04Will it change my tone?
Open strings ring through metal bearings rather than bone or synthetic, which can sound slightly brighter. Fretted notes are unaffected.
