Up until now I have gigged using a single fretted 5 string active J bass. It was supurbly flexible! The active EQ allowed for quick adjustments if I flipped between pick and fingers and for some old school Beatles covers I'd switch to passive mode and roll the tone off to get more of a vintage tone. I went 5 string so I didn't need to worry about retuning to drop D like the guitarists for certain songs.
However, I've found the fiver feels like a battle to play at times, I have smaller hands and reaching round for the low B feels awkward. I recently picked up a 4 string which I felt was just so much more fun for me to play.
So in future I think I will gig with 2x fretted Active PJ 4 strings, one with flats and one which might be in drop D tuning if needed for the set. I love the PJ pickup config and Active EQ for the range of tones I can get without having to adjust the amp's settings. I'm also thinking of something like a Radial Big Shot I/O (V2) for easy switching and balancing volume levels between the Instruments.
