Update:

Having lived with my Gibson USA LP Studio guitar for what seems like a couple of years now, I'll have to say this, sorry Gibson but this particular LP Studio guitar has turned out to be an expensive lemon, reason being is that I can't for the life of me get it to stay in tune and play in tune, I've just spent a bit of time trying to get the intonation for all the strings set correctly and I've come to the conclusion that it's futile because of a couple of issues to do with the positioning of the bridge itself, firstly, the bridge seems to be positioned about 1 to 1.5mm too close to the high e-string side of the neck, secondly, I measured the scale-length (24.75 inch) and the bridge appears to be positioned a bit too far towards the bridge pickup, all the saddles seem to want to be set closer and closer towards the bridge pickup, the strings are fairly new too.

A couple of things I've noticed about the headstock is that the G,B, and high E-string tuners seem to be positioned a bit too close to the edge of the headstock, maybe about 1mm or so, this means that these strings have a bit more sideways kink to them (the B and high E-String are the worst offenders)than the low E,A, and D-strings, because of that the strings tend to bind in the nut slots, no wonder I've had no success with replacing the original Corian nut with Graphtech Tusq nuts, a real Bone nut, a Brass nut and a Zero Glide Nut, secondly, I think Gibson made the neck on my LP Studio with far too much back-angle which is also causing the strings to bind due to too much downwards force on the nut, put simply, I reckon the guitar was badly made at the Gibson factory to begin with, and I paid $2000.00 for this expensive lemon of a guitar?, it really should have costed only $50.00 at best, a friend of mine who serviced my Marshall amp even reckons I paid too much for it too.

So, sorry Gibson USA, this will be the very last one of your guitars I will ever buy, and I was contemplating buying an LP Standard when I could afford one, the only good thing about my LP Studio was the pickups.
