Not sure if this is the correct section so mods please feel free to move. I have MIM 4 string Fender P-Bass and I need some setup advice in relation to the bridge and neck. I don't have a feeler gauge so trying to setup the bass by sight has been pretty tough. The problems I have are that I get a good amount of fret buzz from the 7th fret up if I don't have the bridge saddles raised up super high. The tops of the screw sit flush to slightly recessed with the tops of the saddles. Another problem I have is that the screws on the A string saddle like to unscrew themselves, thus lowering the action and giving me fret buzz. I'm looking into getting a new bridge such as a Leo Quan Badass II or Hipshot A style bridge. Any ideas, suggestions, advice is greatly appreciated. Thanks!!!
