Bonjour my friends. I just got a used bass. Nice 'thru neck carlo robelli' job. It seems all well, but after reading the boards, and playing a bit I notice that when I play the A string(second fret) I get a 'string hitting fret' noise after the note has 'rung' for a couple of seconds. I checked it out, my action is good, but I noticed that the neck has no 'bow' to it. I hear that there should be a slight 'bow' to the neck. I am scared to play with the 'rod-ma-job' thing that everyone speaks of. Should I?? Thanks - K.
