Is this in indication I have too much relief set in the neck? I'd consult Dan's book but the girlfriend redid the book case and I can't find it at the moment.
+1, It's just an indication that you play a lot in that area. I won't even look at a used instrument unless I see a lot of wear in those first 3-4 frets. As Jeff Baxter used to say, that shows that the guitar was played by a "stompin' rhythm player".
Well, for me, it's a sign that the instrument was comfy to play. Plus, I refret almost every instrument that I get first thing, so a lot of wear there means only that the previous owner liked it.
Mine normally are the proverbial steal of a deal on a guitar that didn't play too well for the last guy, so it was pretty unplayed and I just give it a set up and it's like buying a new guitar!
