I am hoping that someone here can help explain a problem I had last night. I was playing my recent MIM Jazz at rehearsal and started to notice a fuzzy sound and the feeling that certain notes were dead. Coincidently, I was wearing earplugs for the first time. I thought that they were the culprits, but upon removing them, the problem remained. In the heat of rehearsal, I couldnt troubleshoot the problem logically. Afterwards, I checked the amp and speakers with another bass and ruled them out. I then went to check the bass and discovered the adjusting screws the control the height of the bridge saddles on the E and A strings were almost at the lowest positions. The D and G's were normal. I know I didnt move them and bass had been in it's case since the last time I used it. Is it possible that they rotated on their own? Has this happened to any one else? Any comments or solutions welcomed. Thanks in advance, A.A.
