hello.. 1st post on this site. Welcome Me!! i picked up a mexican fender jazz for next to nothing a while back, i loved the color and they guy was desperate. anyway, the bass sounds really empty; standard factory hardware, etc. I've always had my instruments worked on by others and I want to fix this one up myself. I'm looking at replacing the bridge, pick-up's, and anything else I can do. The 2 basses i currently use are a modulus which has the pickups came with it & a stuart spector which has the emg-hz that came with it. I'm looking for that classic fender jazz sound with this bass. I'm looking to do all of the labor and I have @ $500 to spend. how would you fix this thing up? I'm just looking for suggestions. I've never done a project like this and I'am learning as I go. thanks in advance!
