Hey everybody. !st question----I live in the northeast usa. We have some extreme weather-- humid, hot summer-- cold, dry winter. I keep my GUILD b50 ( main, everyday player/ recording bass) in a case with a humidifier thingy. Just as the weather turned warm/ muggy the 11th fret on the G string buzzes. In the winter/fall/spring there are no issues. I hate effing with the truss rod--- never like to touch it. Should I just live with this? 2nd question-- My luthier did a total awesome redo on this baby. replaced the bridge with an original specs rosewood bridge ( someone shaved the original down--cheap fix attempt ) --neck reset-- added a brace inside--plays sick. the action is just about as low as anyone would want it. the luthier gave me some shims for the bridge saddle if i ever wanted to raise the action. Do i just cut it even to the width of the opening slot and drop it in there under the saddle? Not sure about this???
