This is what I want to do. I have a 2009 Gibson SG Standard and I want to remove the stock APR-1 style bridge and replace it with a Tone Pros style or Bad Ass style wraparound bridge. I realize I'll have to drill and do all that stuff. I've been thinking about for a while now and wanted to post my thoughts before I get crazy. My question concerns the position of the new bridge. The ABR is angled so the low E string is futher away from the nut. Now all the photos I see of the 70's style SG's the bridge is perfectly parallel, with no rise/run away from the nut. That's what it looks like anyway. If I do replace the bridge, do I have to angle the bridge as such, or can I fit the new post straight in line with nut? I know this is going to de-value the guitar, so from a economical perspective, its a no, but I don't care about that. What I do care about is renduring the guitar unplayable and having to have some major luthier work done to bring it back to normal. I'm also open to people arguing me out of it, albeit within sound reasoning. With all that said, my question is, will I be able to install this bridge (whether I do the work or not) and keep the guitar within the acceptable tolerances for proper intonation and tuning stability?
