I had a full thickness E-ii, My ESP Eclipse is not a full thickness, but to me it's apples & oranges comparing the Eclipse and Les Paul. Two different animals. To me the advantage of the ESP is that I can get one right off the rack and all I would want to change is the string gauge and strap locks and it'll immediately be gig ready. Most of my Les Pauls have modifications to pickups/hardware/frets/nut, but for me the advantage over the Eclipse the Les Paul has is the nitro finish. It let's the wood breathe and be more influential on the plugged in tone, at least to my ears. My two favorite guitars in my collection are my 79 LP Custom and my ESP Eclipse.
