Our Fret Installation
Warmoth's fret installation technique is a hybrid of the compression and glued-fret methods. We first fill the fret slots with a gel-type cyanoacrylate glue. Then, as the frets are pressed in to place, the glue moves to fill in the spaces behind the barbs of the fret tangs. The result is a very stable and durable fret job. The glue has a release agent in it should a refret ever become necessary.
The fret edges are back-beveled to about 30°, and polished to a smooth finish. We can also leave this edge square and unfinished if your request it. Most Warmoth necks are playable as they are received and do not require additional fret leveling. If you desire extremely low action or some other specialized feel, additional fret work may be necessary.
Because wood moves with changes in temperature and humidity, fine fret work is best done after the neck has adjusted to these changes, and been strung up to pitch for several days. For this reason, Warmoth leaves this fine tuning to the end user.
While stainless steel and gold fretwire are harder material than nickel/silver, the same fret leveling/dress techniques can still be used. They take longer to dress, but these harder frets will last much longer than comparable sized nickel/silver frets.
Neck finishes that cover the fretboard are sprayed directly over the frets. Finish covering the frets may be scraped off, or simply left to wear off with use. A fret leveling operation will also take this off.
