I play a lightweight swamp ash Jazz-style bass with Brazilian rosewood fingerboard that I made. I have Aero pickups on it. It is a great playing and sounding bass, but sometimes I would like it to sit a little deeper in the mix of our band. We play blues and r&b and of course the sound I hear in my head is Jamerson and Dunn, the ultimate P-Bass players. I put some TI Flats on the bass and it sounds better than it has ever sounded, but I still want it to cover the frequencies between the bass drum and the low E of the guitar with a bit more punch. I am not really into growl, unless there is a huge amount of fundamental present as well. I am starting to think I need a P-Bass to do what I want. Or maybe a P/J bass to get a bit more tonal variation than the standard P. If any of you tonemeisters out there have grappled with a similar question, I would appreciate your thoughts. Inquiring minds want to know!!
