Hello! I have a 2012 MIA fender jazz bass that has some kind of rattle on the E and A string when I pluck by bridge pick-up. There seems to be no rattling (or less audible) when I pluck by the neck. Moreover, the rattling gets worse as I go towards the bridge. I don't hear the rattle when I play the guitar through an amp. I am not sure if I had this problem all along but I noticed it AFTER I adjusted pick-up and bridge height. And now, no matter how I adjust my pickup/bridge saddle, I can't make the rattling go away. Also, it seems like it is very difficult to make the saddle parallel to the body when just using an eye balling it. I tightened every screws on guitar and the problem still occurs. I have changed the string as well. I have adjusted truss rod with the capo on 1st fret while using the .012 feeler gauge. But again, it seems like I have noticed this problem after messing with the height of pickup/bridge saddle. Is this supposed to be a normal thing with guitars that have "two legged" saddles or does mine have a problem? Thank you guys!
