I have just got a SX 5 string jazz bass, the ash body maple neck and board type. I want to swap out the j pups, bridge (want to shoot for something with 19mm spacing) and tuners. What kind of parts have you guys swapped out on these guys? I need to know what kind of j pups I can drop in, what kind of tuners will fit the holes (4+1), and also how bad do you think the strings are going to be off the board if I do go with a brdige that has that full spacing. I am thinking, past the 15th fret I probably won't care. This probably will be primarily a slapper for me.
