Independent shopping perspective
The Korena take
Built for Floyd Rose-equipped electric guitars, this Black TUSQ XL Un-Lock Nut provides a non-permanent upgrade path for players who want to set each string’s action independently. Its extended ramps spread string tension through the nut slots, while the slot design is made for the string movement associated with Floyd Rose tremolos. A 10-inch radius option lets the nut be selected to match the guitar’s fingerboard radius.
Strong match
Who this is for
- Floyd Rose guitar setups needing independently adjustable action at the nut.
- Players replacing a locking-nut component without making permanent changes to the guitar.
Consider the trade-offs
When to look elsewhere
- Guitars without a Floyd Rose-style bridge and locking-nut arrangement.
- Fingerboards that do not require the available 10-inch radius option.
