String Nut Options

If you want Warmoth to install a String Nut on your neck you must first choose a fret option. If you select "No Frets - Slots Only" the String Nut option will not be available.

Cut and Installed String Nuts

Cutting the nut is one of the most challenging steps in setting up a guitar neck. Let Warmoth do this work for you. We custom-cut every nut to account for the fret height, string spacing, and fretboard radius of the neck, which translates to smooth action and great playability.

Installed nuts must be ordered at the same time as the neck to ensure compatibility.

Traditional Nuts

Standard String Nut

Warmoth can install and cut a traditional style nut on any of our straight or tiltback construction guitar necks.

Available in the following materials:

  • Corian (Black or White)
  • Graph Tech TUSQ XL (Black or White)

Earvana Nuts

Earvana Compensated String Nut

On a traditional guitar, intonation discrepancies will always cause certain chords to be slightly out of tune. Earvana's patented nut technology solves this issue by compensating each string individually for better intonation. The guitar is played the same, but sounds more in tune. Earvana nuts also work with standard frets, bridges, and tuners.

Available in the following materials:

  • Corian (Black or White)
  • Graph Tech TUSQ XL (Black or White)

Learn more about the characteristics of nut materials.

  • Earvana nuts require a wider nut slot than traditional nuts. Converting the slot for a traditional nut is not easy, so be certain you like the Earvana nut before requesting it.
  • This option is not available on Modern Tiltback construction necks.

12-String Nuts

12-String Nut (Drones Above)

Drones Above

12-String Nut (Drones Below)

Drones Below

Most 12-string guitars are strung with the higher octave strings on top (drones above), so they are struck first when strummed. However, some players prefer their guitars strung with the drones below. We can cut our 12-string nuts either way.

Available in the following materials:

  • Corian (Black or White)
  • Graph Tech TUSQ XL (Black or White)

Floyd Rose Shelf Prep Back View

Floyd Prep Rear View

Warmoth can prepare the shelf for a Floyd Rose locking nut. These nuts, which clamp the strings in place to improve tuning stability, may be purchased as part of a complete Floyd Rose tremolo system, or separately in our Hardware section. They feature a 10" radius, and ideally the fretboard radius should be 10" also. However, they will function correctly on any neck radius between 9" and 12".

Nut Width Identification

To properly prepare a shelf for a Floyd Rose nut, we must know its size number. This number is cast into the bottom of the nut, and begins with "R" on right-handed nuts, or "L" on left-handed nuts. These numbers correspond with nut widths, as shown below:

Right Handed Floyd Rose Nuts:
  • R2 = 1-5/8" Nut-Width
  • R3 = 1-11/16" Nut-Width (Narrow string spacing)
  • R4 = 1-11/16" Nut-Width (Wide string spacing)
  • R5 = 1-3/4" Nut-Width
Left Handed Floyd Rose Nuts:
  • L2 = 1-5/8" Nut-Width
  • L3 = 1-11/16" Nut-Width (Narrow string spacing)
  • L4 = 1-11/16" Nut-Width (Wide string spacing)
  • L5 = 1-3/4" Nut-Width

Sizes R3 and R4, and L3 and L4 are all for use on necks with a 1-11/16" nut width. What differentiates them is their string spacing. Size 3 nuts use a narrow spacing similar to that of a 1-5/8" nut width, and work well any time a player wishes for a little more margin on the edges of the fretboard, as on necks with binding. Size 4 nuts offer a slightly wider string spacing that feels more natural to some players.

  • The Floyd Rose Nut Prep option is available on Modern and Modern Tiltback construction necks only.
  • There are many Floyd Rose-licensed locking nuts available. Though they may look similar, they do not all share the same specs. This option is specifically designed to work with the Official Floyd Rose nuts made by Schaller.

LSR Roller Nut Prep

LSR Nut Prep

Warmoth can prepare the nut slot for an LSR Roller Nut. These nuts, which use ball bearings to ease string movement and improve tuning stability, may be purchased seperately in our Hardware section.

The LSR nut is only available on right-handed guitar necks using a 1-11/16" nut width. It can be used with any straight fretboard radius between 9" to 11", or the Warmoth Compound Radius (10"-16").

  • LSR Nuts require a wider nut slot than traditional nuts. Converting the slot for a traditional nut is not easy, so be certain you like the LSR nut before requesting it.
  • This option is not available on Modern Tiltback construction necks.

String Nut Blanks

If you desire to cut your own nut, Warmoth offers nut blanks in the materials listed below. Nut slot files are also available in our Hardware section.

Material Characteristics/Applications Sound Workability
Bone Hard material with a vintage look, must be cut cleanly to keep strings from binding in slots. Bright and clear, with a detailed sound. Hard, dense material. Bad-smelling dust.
Brass Hard material polishes well and looks good with gold hardware. Great sustain for bass and slide guitar playing. Bright with very good sustain. Slow-working, dust can clog files, gets hot when power-sanded.
Nickel Made of the same material as our fretwire (18% hard nickel/silver) so it matches sound and look of frets. Polishes well. Very bright with excellent articulation and sustain. Very slow working, gets hot when power-sanded.
Corian Hard synthetic material takes a fine finish and is available in large oversized blanks. Balanced, clear, even sound. Cuts slowly but evenly.
Graph Tech TUSQ XL TUSQ XL is an ivory-like material that is Teflon impregnated. Teflon is 500% slipperier than graphite. This is great for use on electric guitars that get tremolo use or have tuning stability issues. It is also great for someone who bends notes often. Well balanced tone with a bit more warmth. Easy to cut, less shaping required with pre-molded blanks.
