Hey everyone. I plan on buying a fretless Jazz from Rondo next week, and then I'm going to begin the quest to upgrade it. I just have a few problems. First off, I would like to equipt it with a BadAss II bridge, but I'm not sure if one would fit, do they fit correctly, or will I have to have a different bridge? Secondly, is the pickups. I have some great ideas of pickups, but I'm having troubles finding some that'll fit the place where the old pickups go. And when I do install the pickups, will I need to install a brand new preamp aswell? Also, could you recommend some pickups to look into getting, I found some barts that would fit, but they are for a 5 string (would it matter?) But other than that, I havent really found anything too much. Thanks for your help!
