Hey all. I've got a 1990 MIA Jazz bass with Lace Sensors. I love the way my bass feels, but I'm not too happy with the tone. I'm running it through a Carvin R600 head and an RL2x10 or Goliath II or both. Still... it's not quite the tone I'm looking for. Will replacing the Lace Sensors with EMGs make a difference? Or should I try a new amp? What's the deal? I almost bought some used EMG jazz pickups used for $75, but the guy at the store told me it wouldn't make a big difference tonally. What do you guys think?
