I recently acquired an Ernie Ball OLP MM5 baritone, which is a 30" baritone 6 string. It was quite a steal, considering I got it through trading a shit Epiphone that I never used.
However, when I went to install some new pickups today, I noticed that the bridge and pickup cavities were completely misaligned...
As you can see here, when the bridge is aligned with the mounting holes, it doesn't line up with the string-thru holes.

The discrepancy is highlighted here; the rulers clearly show the relative misplacement of the bridge and pickup cavity.
An additional problem I noticed was that I was unable to intonate the G string; moving the saddle all the way back was not not enough to flatten the fretted octave relative to the open string. When the bridge is aligned with the string through holes, it it farther back (which could account for the intonation problem) and is more closely aligned with the pickup cavity.
So I'm wondering, could I just re-drill the bridge into place relative to the string holes? That seems to be more where it was meant to be. However, doing this would make it quite close to the previous mounting holes, which I imagine could cause some structural issues. Is this the kind of thing better left to a tech?
Thanks in adavance!
If you're handy then it can be done - in the past I've drilled out to a bigger dowel size (around 6-8mm depending on existing holes) dowelled the holes with hardwood dowels, drilled new holes and voila. You really need a drill press with a depth stop or a fucking super-steady hand, though.
Depending on how far forward the 1st and 4th strings are ('E' and 'D' in E standard) are when intonated, moving the bridge back would not be a bad idea if you're struggling to get full intonation range. A few mm is all you need, and as long as you can still intonate the furtherst 'forward' strings then you've got a winner!
