Know the specs: Having a reference point helps. Gibson’s engineers recommend a 1.6-millimeter distance between the strings and the pickups for the bridge pickup, and 2.4 millimeters for the neck pickup. In the 1950s, it was 1.6-millimeters for both pickups, which may have reflected the lower-output, unpotted standard of the day. However, if your guitar sounds too muddy, add some distance on the bass side. If it’s too bright, do the same on the treble. And adjust to your own sonic desires.
