Re: Trem Angle
I would maintain that the trem doesn't have to be 100% precisely level. IMO a number of imperfections in the system can lead it to not be 100% level. It could be a minute variance in the scale length, imperfections in the fine tuners, expansion or contraction of the wood, or even something like a slight variance in the way the springs are flexing. Remember what you're doing is canceling vectors; the springs counteracting the tension on the strings. This idea that eyeballing it makes it perfect isn't sound IMO. This is why I use a good tuner to level my trems. Keep the back plate off, tune, and adjust the spring tension accordingly. The real goal is making sure the thing doesn't slip out of tune and returns to pitch when the trem is used. A machine works much better than your eyes do.
Again, just my humble opinion. It works for me though.
