Just took the plunge on some Nordstrand NJ4SE pickups. They are on their way from Arizona to me now. This will be on a FRETLESS bass so slapping [ although that will happen ] and bright shiny sounds are not a concern. Wondering what your experience is with them passive and with a preamp. It goes without saying that it is a personal preference [ passive vs active ] and there are all the other obvious factors. So having said that, what has been your experience with these pickups active vs passive? And if active, what preamp? If I go active, I may just stay with Nordstrand preamp that is Vol/Vol/Tone[pull passive]Mid[pull frequency]Bass/Treble stacked. Any other suggestions for preamps with these pickups? Again, the focus is fretless. It is kind of hard to imagine being totally happy with passive as having all of that tone control is very nice. Thanks for any opinions!!
