I thought to start a new thread here, rather than continue in the "Design Your Own SG" thread. The problem is that both "E" strings are slipping off the lower frets. Chords are not a problem. BlackSG91 thinks it may be the nut, but it doesn't look like it, and I'd hate to remove such a nice aged part as this. (ctrl + to zoom in) Gillean suggested a re-fret, and that's most likely, but I think it's just a few frets that need replacing. It was re-fretted a four years or so ago, and I think some of them are too short, and causing the slippage. This one shows what can happen to string with a pick stored under it. Any thoughts chaps?
