I like my pickups really close to my strings so they can receive more vibrations and make it louder without having to crank up the volume on my amp. My jazz bass is set up like that with the E and A pickups slightly lower than the D and G for obvious reasons and all four strings give out a nice strong and loud signal. Howveer, for my p-bass, that's not the case. I lowered the E and A pickup so the strings don't clack against the plastic cover and the D and G pickup nearly touching the pickup. Despite this, the D string gives out the weakest signal, then the G, then the A, then the E. What is going on? Do P-basses normally have this issue?
