Okay I love my DJ4 but when it comes to remembering what knob settings get what sounds, I'm as forgetful as a bird who.....oh I forget. Usually I play through a Line6 Bass Podxt so I leave my knobs alone and let the bass pod do the work in getting me a jazz or a rock sound when the song calls for one. Yes I'm also lazy...but it works. When playing straight through a 1x15 with flat EQ, I like the sound of full neck and bridge pickups and tone turned to 8 o'clock (from where you look down at it). I find it gives a rockish sound. For something more jazzy I simply switch off the neck pickup. I'd love to hear what your favorite settings are and what type of sounds they give you so that I can try them out for size as I'm still figuring out the bass. Please describe the knob positions with a reference of 12 o'clock pointing straight down at your feet.
