So, I got a used Fender Aerodyne MIJ jazz bass 11-12 years ago, probably made around 2002-2003. Always played 5- or 6-string, so I never used it much. Some rehearsals, a few gigs. The setup was ok but not great, the pickups had a lot of noise. Liked it, but didn't love it. Always grabbed a different instrument when I was practicing at home. Had some spare time the last few weeks, so decided to change pickups (got a used Aguilar P/J set cheap). shielded it completely, changed strings, adjusted the truss rod and string height, and it feels like a new, fantastic horn. I think I'm starting to love it.
