I like on boards for two reasons - 1 - reduced noise due to a higher output from the bass. 2 - pinpointing a specific sound. While I have on boards on both basses, I found that I have, outside of pickup blend, maybe three very similar EQ settings - like a little more low end, or a bit more mid. Once I find the sound I like, I leave the EQs on the bass pretty much alone. I would go passive otherwise.
