Not sure if this should go here or in strings but here it goes... Replaced a Fender-like bridge on a bass with a Hipshot Type A. I chose this bridge because of the similarity to G&L bridges, which I think are fabulous, and because I've had a good experience with Hipshot products. New mounting holes were required, because the old bridge did not have a standard Fender mounting pattern. I measured about a dozen times to center the intonation region. Then I measured again. I was a bit concerned because the Hipshot A's stock usable intonation region was narrower than the existing bridge. The bass was wearing 4+ yo LaBella 760s...I set up the new bridge and everything aligned perfectly. This is when my trouble began. A nice feature of the Hipshot A is that it allows for quick changing of strings due to the ball end load design, so I thought, I wonder what this might sound like with new LaBella's. So I put them on, did a set up, and found that intonation point for the D string was very different. So different, that that the stock parts could not achieve correct intonation. I was able to find a longer lead screw and everything worked out, but I had never seen something like this before - a huge change of intonation region with a new set of strings that were otherwise exactly the same as the older set. Anyone of you ever seen this and can explain what might be happening? I'm kinda freaked out by this as I'm now concerned (OCD warning) that the bridge may be mounted suboptimally.
