Okay, I've done searches and did not find what I was looking for. A luthier is making a fretless bass for me. I was wondering which pickups are better for "mwah". Bartolini 9Js? Dimarzio Ultrajazz/Model Js? I have bart soapbars in my pedulla thunderbolt and I really like them but, we're talking about active pickups and preamp here. I think he wanted to run the Barts without a preamp, just passive (correct me if I'm wrong). So what do you think will give the bass more of the "mwah" factor? Passive or active? Last question: how do EMG preamps work with Bart 9Js? Thanks in advance!
