I have the Model P and J DiMarzio pickups in a banger bass i have.
It has a series/parallel for each pickup, and a series/parallel between the pickups, aswell as an in/out of phase switch (push pull pot). And is a vol/vol/tone setup.
What id suggest is vol/vol/tone + a series/parallel switch, to put the pickups in series or parallel with each other, out of all the other options i have, thats the one i use the most
If you want to keep it basic, you could always do vol/vol/tone/tone? (volume and tone for each pickup)
Or, as bassist 4 life points out, probably use them with the active preamp.
