...I love stainless and EVO gold fret wire and will not go back to regular nickel silver fret wire. In fact, I just bought two pounds of stainless steel fret wire from Jescar (enough for 12-14 guitars) and will use this on all of my guitars, electric and acoustic, when the time comes to refret.
Also, older files tended to wear out from the harder stainless steel fret wire, but files made in the past 5-10 years are harder and don't tend to wear from stainless, though it does take a little more time to level. Based on this, there should not be a significant upcharge for stainless steel refrets at this point.
^^^My boldface, and a point that deserves repeating, IMHO.
I have spoken to two skilled and highly reputed builders (whose names are notable but I will not divulge, one of whom did the SS refret on my Tele), and this whole "upcharge for SS" thing is largely overblown. Upcharging clearly benefits the luthiers/techs out there because folks repeat it, and thereby believe it. But in the experience of these two notables, the add'l wear on tools as justification for hiking prices of SS is minimal, yet has become accepted in the marketplace.
Now I am no builder, but this is from two who are; nevertheless, I am subject to what the marketplace deems for a SS refret. But for those who actually know
because they do their own, they will note that actual price differences are far less than what people make it out to be.
Thanks, Tedtan for sharing your experience!
