I just got a new bridge for my fender p bass from this store but its used. It works fine its just theres this messed up white stuff over the sattles that disallows me to move them up and down. I got most of them free but the last one wont move a single budge. All the other strings are normal except the E Its tuned properly but its so lose becuase I had to take it off to fix the saddles and yet I still cant move the saddle up or down those lil screws are unmovable! Did I really fudge over my bass?
