Currently, I'm back to a simple system. All my basses are passive 5-stringers, running through Empress Compressor into Aguilar Tone Hammer.
- My all-around middle-ground main is a Fender P with NYXL strings.
- For an upright-ish vibe, I play another Fender P with TI or Dunlop Flats.
- For improved articulation in smaller ensembles, I play a Fender J with NYXL strings.
In your shoes, I would
subjectively see two alternative orientations.
Case 1) "I already have a P with flats (old-school world) at one extreme end and an active JJ (modern world) at the other extreme end, I should throw in a bass where I want to be in-between those extremes." In that case:
- Your passive J or G&L L-1000 seems to occupy this gap already; assuming you install round wound strings.
- If you are a P fan you could get a P / PJ with round-wound strings to sit in-between those extremes.
Case 2) "I already have a P with flats (fat neck sound) at one extreme end and a JJ (scooped sound) as the middle ground; I should throw in a bass with a fat bridge sound for the other extreme end." In that case:
- Sadowsky Modern is a strong contender if you are going for a sterile, versatile, Hi-Fi sound.
- StingRay or G&L L-2500 comes to mind in case you want a more aggressive sound.
Since I don't need anything beyond the J bridge pickup at this time, I sat in Case 1. But, I have friends who would sit in Case 2.
All of that is my
subjective opinion, not universal facts applicable to all players, but I hope I could help you get inspired.
