Anybody know off hand, just exactly where, in mathematical terms, the pickups of the classic basses are placed and why? What are the locations of the: 1. Jazz Bass bridge and neck pickups 2. Precision Bass pickup 3. Music Man StingRay pickup(s) as those positions relate to the scale length or harmonic nodes of the strings? And why did LF (or whoever) choose those locations? For example, I measured my single-pickup StingRay, and the pickup seems to be centered somewhere in the area of 30.5" (not exactly, but it was a quick measurement) from the nut on a 34" scale. I would have expected it to fall at a major node, but it doesn't seem to.
