I have a guitar with a floating trem that I keep in standard tuning. I've heard that the bridge is supposed to be tilting slightly forward when setting it up properly, so that's how I've always had it. If I wanted to change to half a step down tuning (with 10's, this causes the bridge to sit pretty much parallel to the body), is this damaging to any parts of the trem? How much does this throw intonation off?
Also, what actions specifically cause damage to the knife edge?
