I want to swap out my Bartolini Pups that's in my Ibanez BTB 6 string bass( They don't seem to have that ballsy " growl" I'm looking for. I've received suggestions that replacing them with a set of Aguilar DCB -D4 pups may give me what I need. My question: If I make the swap, will the Aguilar pups work with the original pre-amp system already in the bass OR will/should I have to swap out & put a comparable pre amp in as well. Say an Aguilar OBP-3 preamp????
