Hi everyone, I recently picked up a used Rockbass Corvette 5 Passive and although I love it, I really need to take some time and tinker with the action, bridge, Just a Nut, etc. I've watched the vids on Youtube and still not getting how to adjust the actual string spacing (seems very narrow). Will that move by adjusting the saddle screws or are they just for the string action? Also, how do these compare to Squier Jazz basses in terms of quality and sound? Pickups and neck seem ok and I like the finish on the body just not familiar with their bridge/nut system. Any lovers/haters out there can help shed some light on these? Thanks!
