Can anyone tell me about the pickups in the Fender MIM FSR Jazz Bass. I've looked around and can't really find anything too specific. I might want to change them but they really don't sound too bad. Are they ceramic, are they considered poor quality...you know the drill. Has anyone kept them and used them? What do you think. Sometimes I just can't leave well enough alone and over the years I've bought a lot of pickups. There have been times I think I should have saved my money. Thanks for your thoughts.
