I've used nickle round wounds on my basses since 1976. Prior to that, I used Roto-Sound Swing bass steel strings. They did so much damage to my frets that I switched to nickle coated steel. Recently I couldn't find any super long nickle plated steel round wounds locally and purchased a set of DR HI Beam stainless steel strings. I really love the sound of those strings but I'm very concerned about the potential for greater fret wear. I noticed on the string package that they quote Marcus Miller as saying "They do not eat my frets". If you've used the DR Stainless Steel for a while, would you say this is true or are all SS strings the same as far as fret wear goes? Thanks!
