Yeah I guess I'm not looking that closely at the guitar to be 100% honest. It looks good, feels good in my hands and sounds good coming out of my amp so I'm happy. I got it for $1,000 on close out so to me it was well worth the money and IMHO a Gibson SG is the greatest guitar ever made for slide guitar and that is my primary function when playing in the band.Good point. To my eyes that doesn't look like fret wear. It looks like the typical Gibson fret profile that really should be crowned better.
The ES-335 that I have on hold has properly crowned frets, but the frets are too low (so I guess too much material was removed) and they have not been polished. If I end up buying that guitar I'll polish those frets and it'll be good. I have not seen any other issues with it.
I did buy a Les Paul Special a few months ago and I decided they frets had to be recrowned. I even found a couple of high spots with the fret rocker. I know that's not supposed to happen on plek'ed guitars, but the high spots were there, although minimal. Those frets were not as flat as on pre-plek years, but nevertheless I thought they were too flat for my liking.
I have been wondering if there might be a more "legitimate" reason for flat-ish Gibson frets. Perhaps somene's thinking to do it that way to extend the life of the frets. more surface area = less wear = longer life. If that was somehow ever the intention I still think they made them too flat on many of the guitars I've seen.
