It came fom the factory with corroded 9-42's instead of 9-46's, and it was setup poorly to boot, very poorly. New 9-42's didn't fix the problem. Raising and lowering the bridge didn't fix the problem. Adjusting the trus rod was futile, no sweet spot with 9-42's. Another Gibson fail out of the box. I'll try and set it up with 9-46's. If that don't work, 10-46's. If it don't sync up at 10's, this one's coming back. Either way, this was my last Gibson purchase! ...corroded 9-42's on a new Les Paul??? lol. It took a luthier 3-months to get my J-15 right he calling the setup from the factory "juvenile". The Firebird One ended up as wall art after a good initial experience. The SG 24, it took a long time to get that one to sync up, the wood...too fresh, but it's curing and playing nice now. I'm done, enough is enough with Gibson. I got no more time to waste on this ...%rap.
