I'm gonna say yes and no on this. If Paul believed they added to the tone, they'd at least be an option. There's a reason he puts every single part on his guitars. Sometimes the consumer finds it hard to trust the expert...
Yes, this! ^^
The following rant is not a specific response to the OP, because I don't care what he or she does or doesn't go shopping for.
I just want to talk about frets and guitars for a bit.
Guitarists often want the 'classic' tones. We love the tone of old Strats and '59 bursts, and so on. All those classic, iconic guitar tones were done using guitars that employed certain materials, including frets.
Every part that touches the string affects the tone, according to Paul Smith, who designs the guitars and knows what to listen for. I've been playing PRS since 1991, and the guitars have never sounded as good as they have in recent models.
Why would anyone want to mess with "never sounded so good?" I wouldn't.
Then, too, I own a 1965 SG Special with traditional frets - in fact, the frets are very low 'fretless wonder' frets Gibson used at the time -
that has never been re-fretted. I know this because my brother bought the thing new and gave it to me in 1967. And both he and I played the heck out of it. Sure, there's wear on the frets, but 54 years down the road? Lots of human beings don't live as long as the frets on that damn guitar!
Part II
People want their friggin'
instruments to be immortal, but seem to be far less concerned that the
music they create is worthy of becoming immortal.
"It's only a hobby for me, Les. I have a day job and a family to support. I don't have time to make really good music."
"Let me introduce you to Charles Ives, an orchestral composer of international standing, whose works are still performed today, 67 years after his death. In addition to being a composer, Ives was the actuary and an exec of an insurance company, who frickin' wrote books on estate planning and tax planning. Don't tell me you can't make good music because you have a day job."
