I bought a Cort action 4 bass recently, and took it to a luthier who made all the necessary adjustments to it. Now it is very comfortable, but i have 1 problem. The strings rattle at the saddles. Its not the saddle springs. The saddle screws rest firmly on the plate. And the strings rest firmly on the saddles. Once again the luthier is a professional who makes guitars and did an amazing setup. I would take it to him again, but hes in a diffrent city and i cant go right now. I am 100% sure its the bridge, since it does this on every fret and not the nut. Even the very last fret buzzes. The strings are also brand new. What do you think?
