Increased note clarity on the top end, kinda cold sounding and not as warm as nickel silver frets. However they play amazing and once polished will stay polished for a lot longer than silver nickel.
Ive used Jescar on both of my LP refrets; 0.110x0.057.
I recommend you find a luthier that has the tooling for SS fret dress and the time to properly fret dress. I emphasize the latter because I’m running into a problem of a luthier that has the skills and the tooling, but doesn’t commit the time it takes to properly dress them. the end results are gritty frets.
Plan to commit a month or more with whomever you find and ask about prior problems of gritty feeling frets from customers. I found out only after I had mine done that others had complained of it but it was not documented anywhere - dudes talented but a dick when he doesn’t want to do something and will turn the work away or rush it.
Over the years (15 to be exact) I've had several guitars re-refretted with Jescar 57110 (as you mention). I've into this exact issue with one guy who was too lazy to properly polish them up.
Long story short. Phil Jacoby was my number one choice. Still is, but is so buried in work it took me a year to get my last guitar back. As all previous 10 refrets, it was perfect.
I recently found a guy in Austin, TX that is marvelous. Pete Skermetta. He did my last 2, and I'm pleased with the work. But Phil is the most absolute, downright pickiest perfectionist I have ever known. And, there is some kind of magic that comes back with every guitar he's ever done for me. I swear, I cannot explain it. It's of course a personal and subjective opinion, and I'm sure a lot of this is simply "in my head", but it is there, and I feel it everytime I pick up one my guitars Phil has refretted.
For what it's worth, the only other guy I've run into at this level is Joe Glazer. These 2 guys are becoming inacessible to common folks like me these days.
You will hear many horror stories about Phil Jacoby. I feel like I've read them all. Particularly from one member here who is an extremely dogamtic and self proclaimed expert on everything gear related under the sun.
But for me, as far as stainless steel frets in general, it's like Franks Red Hot.......I put that shit on everything.
