I have a Fender Jazz Aerodyne bass, which i got recently. I have put Ernie Ball 105-50 gauge strings on the bass, replacing the 100-45 fender strings that came with it. I did this as i favour the heavier gauge, but having done so, have run into some problems. The heavier gauge first off caused a lot of rattle on the frets. i set about tweaking the setup, but have only been able to get the rattle to stop by increasing the action. The truss rod position seemed fine. Now the action is uncomfortable and the beautiful playability is not there. What i want to know, are heavier gauge strings just not able to be put on this guitar without causing major problems to the action/setup? Need to know whether i should move back to 100 gauge or to try and set it up for 105s the best i can?
