I had made up my mind to go with a SPJ, but then I had the idea of adding a ptone to my AB1 and going the SJx3 route.
This opened up my current can of worms….
Do you have a body style preference?
I’ll admit here. I’ve never been a traditional bass guy(J or P). I always thought if it was one or the other I’d be a J all day. I think the real outcome is opposite. I seem to feel more comfortable on the P. I’d start there.
if your putting a P tone in the long scale it’s gonna give you something different but it’s not a single pup P. IMO a SP offers the most contrast to any long scale.
I’d perhaps keep the electronics simple on your first super and find how you bond with the medium scale to begin with. If you find yourself still coming back to the AB then perhaps putting the funds to a 3x long may be an option you’d prefer over a loaded J.
food for thought
I know @dtsamples has a really nice PJ in the classifieds right now as another option
