This has been via guitar center. I got my third ES Les Paul today. The first one was so bad I couldn't believe it. My old Ibanez Gio kept better tune. Just getting it in tune at all took about 10 minutes. I tried nut sauce. That helped a bit, but as soon as I strummed a chord, it all went out. Let the guitar sit overnight, same thing the next day. Whoever cut the nut must have been using a string gauge from an alien planet. Second guitar was the same story. It was all I could do just to get it to stay in tune for more than three chords. I've encountered this before. I've got a 2012 Midtown that took a lot of graphite to get going, but it eventually came around. Trust me, I'm the patron saint of Gibson tuning issues, but THIS is crazy. Got my third replacement today and it's once again not able to get in tune. I don't know what the deal is. This is the worst I've ever encountered. Maybe I'm super unlucky. To top it off, I got a 339 from CME this week as well, and guess what? Same thing. The nut needs serious, serious work. I've never seen guitars so hard to tune from the factory.
