I have a new Full Circle pickup, and the un-threaded posts aren't large-enough diameter to fit snugly into the existing holes in my my bridge-legs. They wobble in their holes, and the feet fall out as soon as I turn it vertical. Fishman tells me that it should make no difference, string tension should hold the bridge together. Their opinion is that when the bridge pops off after less than 3 minutes of playing it must be due to my luthier not cutting it so the underside is perpendicular to the face. I put a small carpenter's square on the face of the bass, between the strings, and the back side looks perpendicular to ME. I see the size of the un-threaded posts as a problem. Does anyone agree with Fishman, on this? Do un-threaded posts, so undersized that they wobble, actually have no bearing on the bridge popping off? The bridge stays on fine with the original adjuster wheels on, even when playing slap.
