Well, I have (2) P's (one active-an amazing Xotic, and the other a real-deal passive '69, and I have (3) J-basses
(2 & 3 band active eq's, the other passive) and several other basses with a variety of pups- Delanos, soapbars, MM's etc. Oh, and the J's are anything but "thin-sounding" YMMV.
Me- I'm just a mere mortal, working at clubs and other functions- I play what I want!
Good thing I don't get any session calls, I'd have a terrible time deciding which bass to play and would not care to grapple with an Engineer, Producer, or anyone else for that matter.
(TBT, I have done a very few sessions-demo tracks & such- & don't particularly like the recording process, wearing cans & such, but that's just me).
Carry on.
