I have a WMI made SE Custom 24. The 6 knife edge screws for the trem are not quite all level. 3 bass side ones are level E and G string ones are slightly down and the B string one is a bit more. It's not a big difference, probably a few thou, but I would think given the bridge design these should all be perfectly level no? It came from the factory this way (I watched the guitar store employee open the box when I bought it.) Should I make them all level?
