Schaller Locking Nut Right R3 CH

I've installed it using the two small screws directly into the wood. The installation went quite smooth.

- You need to flatten the nut slot excess in the back using a filer. You can lower the string action at the nut if you want. Is good by default but you can improve that too...don't file too much though.

- After that I just centered the nut by tensing the strings over it a bit and put the screw right in without drilling.

I'm using this locking nut in combination with a Schaller FS-C StopTail with microtuners on a DIY LesPaul (look for a review on that one)

This is the real deal Schaller Locking Nut replacement and the quality is so solid, it's not even worth looking at other alternatives!

It's rock solid, the plating lasts and doesn't corrode easily, and most importantly.... It keeps your strings locked and in tune at all times.

I bought this to replace the cheaper Floyd nut on my Charvels and this immediately improved tuning stability. It just works exactly as a locking nut should.

It's the R3 size nut so it'll fit the Charvel San Dimas and So-Cal guitars with no problems at all. You get the option of mounting it through the neck (using the two long bolts) or simply screwing it down via the top (which is how i use it).

Obviously measure the nut width of your guitar first to be sure it will fit. If you need a different width or spacing, they make other types R2, R4 etc.

Its a 5 star rating from me!
