recently bought a secondhand epi thunderbird in excellent condition,good frets,no warps or twists etc.problem is no matter how i set this bass up i cant get rid of a lot of buzz at the first fret on the E,and sometimes on open E if i play hard.ive tried as much relief as the neck will allow,vice versa and everything in between with various action heights,and also new strings.still buzzes!more relief puts buzz in further up the neck,so the best overall position seems having very little relief.as you can imagine this makes that first fret a nightmare!
any suggestions greatly appreciated
PS dont do jokes about the power of christ compelling it!!!!!!if only that would work!!!!!
