Fretwire Materials

Warmoth offers three materials of fretwire. The same fret leveling and dress techniques can be used on all three materials, though Stainless Steel and Gold will take longer.

Nickel/Silver

This is our standard fret wire, similar to that used on modern Fender® instruments. It polishes up well, and plays and sounds fantastic. It is drawn from 18% hard nickel/silver, and rated at HV 170 on the Vickers hardness scale.

Stainless Steel

This is our premium fret wire. Stainless Steel frets feel faster and smoother than Nickel/Silver, and also last much longer before fret work is needed. There is no discernable difference in tone. This top-quality, German-made Jescar fretwire is rated at HV 300 (+/-20) on the Vickers hardness scale.

Gold

Our Gold fretwire is almost as hard as Stainless Steel, and offers the same fast, smooth feel. The gold color is solid throughout, so it will never look worn or turn brassy. This top-quality, German-made Jescar EVO wire is rated at HV 250 (+/-20) on the Vickers hardness scale.

Our Gold fret wire is EVO hypo-allergenic, for those with allergies to nickel.


Fret Installation

Warmoth glues and presses the frets into place, resulting in a very stable and durable fret job.

We then back-bevel the fret ends to about 30°, and polish them to a smooth finish. We can also leave the ends square and unfinished if you request it.

Warmoth does not perform fret leveling. Most Warmoth necks are playable as they are received and do not require fret leveling. However, because wood moves with changes in temperature, humidity and string tension fret leveling may be required. This is best done after the neck has been strung up to pitch for several days and allowed to adjust in the assembled state. For this reason, Warmoth leaves this fine tuning to the end user.

On necks with bound fretboards, the binding is installed before the frets. The fret ends extend over the binding all the way to the edge of the fretboard. This results in the widest, smoothest playing surface possible. It also makes fret maintenance easier and less expensive.

On finished necks with Maple fretboards, the finish is sprayed directly over the frets. This finish will wear off quickly with use, or it can be scraped off quite easily. A fret leveling operation will also take it off.

You must choose a fret option if you want Warmoth to install a Nut or a Finish on your neck. If you select "No Frets - Slots Only" the Nut Install or a Finish options will not be available.
