I know little to nothing about tune-o-matic bridges. I own a Dot BP and just noticed the intonation screws may be on the wrong side. The screw heads face the pickups, not the string guide. I've looked at a few different images online and I found pictures where they are face both directions. Considering the individual saddles can be rotated I'm wondering if it matters which way the screw heads face other than ease of access. So, my question is, how do I tell if my bridge is backwards, assuming there is a backwards?
