Alright, so I've been setting up guitars for a few years now and I've gotten pretty good at it. BUT all these years Ive been confused on how to setup my Ibanez SA bridge.

My question is this....
What part of the bridge is supposed to be parallel with the body?
.The saddles?
. Or the actual bridge itself?
