I've got the action at the 12th fret on my LP Studio set as per Gibson factory specs (5/64 for the low E-string and 3/64 for the high E-string), the guitar seems to be playing well and I've got the string intonation for each string adjusted as close to spot-on as I can get it (the A-string was a bit finicky to adjust but I got there in the end)so the guitar is playing as well as it can, I think it's ready for taking to uni next week, in that case, I'm calling it "job finished".
