A tech told me recently he likes stew mac fret wire as it tarnishes less than Dunlop. This tells me that theres less nickle in the stew mac. I really like Dunlops "soft" higher nickle content wire in terms of tone and guitars I have had with regular dunlop 6100 sound fine, but Stew mac makes a fret wire shorter and narrower than a 6100 and wider than a 6105 that looks interesting to me. Has anyone used any stew mac wire and found it to be brighter than Dunlop? Thanks!
