I dunno, Nelskie, but I had the same problem with my ESP, compared to my other guitars. Same 25.5" scale, different bridges (2 piece LP style). Was having problems with the guitar, so I disassembled the bridge and took out the jack (was having grounding issues). Changed strings (I use the same D'Addario .010s), and did a general setup, including tightening the retaining nuts for the tuners and adjusting string height. Fiddled with the string height, and must have found the "sweet spot." The action was a bit too high on the lower E, A, and D strings, and too low on the G, B, and E strings. The TOM was no longer perfectly level, but the action is MUCH better, and the strings feel almost too slack now, and the guitar plays like brand new. Time will tell how well she'll hold a tune.
Mystifying stuff, guitar setups. Next time, it's gonna need a fret recrown and a truss rod adjustment, but for now, it's good!
