Without question a P bass pup. MM in the sweet spot near the bridge and P in sweet spot at the neckish position.
I'm offering that with my new company, Lower Groove Guitars as an option on all basses among some other interesting options.
Best of two different worlds and together the sound is huge.
In my opinion better than two MM's together.
