Doink's right on the money, the pick trick only works if all guitars have the same neck pocket depth, neck heel depth, amount of neck shim, etc. Look at the edge of the trem where the knife edge protrudes through. This is a good reference point to see how close to 90 degrees it is. Actually if you have a thick neck shim in, you'll want the knife edge angle slightly up in the back of the trem. The way Ibanez shows in the 'pamplet' they supply with a new guitar is the bottom of the trem parrallel to the top of the body. Since you can't see the bottom of the trem use the knife edge protrusion as it's parallel to the bottom of the trem.
