I currently own a MIA Fender Jazz Bass w/emgs. It has a great tone and I love how quiet the EMGs are. The highs and mids are real nice but it lacks lows and lowmids. So I'm looking to get better lows. What would you suggest? New pickups or add a preamp (will one work well with the already active EMGS?) or both? If anyone has or has heard a really bassy Jazz bass please let me know how you did it thanks.
