I checked the DiMarzio Relentless pickups. They have Jazz Bass versions too.
This summer or the Fall, I'm making a Warmoth Jazzmaster Bass IV with jazz bass pickups. I'll get these pickups for it.
I remember when I was rehearsing with friends many years ago, one time we used a Yamaha bass in one of the studios and the sound was so good! Nowhere near all the basses we had tried so far. It was tight, with a cool mid punch, super cool bass sound. These pickups reminded me of that.
