Haven't used Nickel but me and a buddy of mine did try a set of Martin (Eric Clapton's) last year, he owns a Martin D35. About a month later, he came over and said "Man, my frets are wearing out like crazy". I looked at mine and holy cow, they have some divits too! And only after 1 month of playing.
Well we both immediately switched brands. He went with a set of Dad's and I put some Earnie Ball Earthwood's on my 114CE. No additional fretware this whole last year, and we play a lot. Strings are lasting very well too.
Anyone else experienced this type of premature fretware? Is it possible we may have some "soft" frets?
