Has anyone ever had issues with "radiused" bridges? I'm having an issue with my custom Roscoe bridge (made by Hipshot), I'm having to mill out the D saddle slot by about 1/64" to get the action low enough to where it's consistent with the other strings. This Roscoe is my favorite fretless bass of all time, the four strings that are "in" have an incredibly killer sound, and they're so comfortable to play that I couldn't wish for anything more. But that darn D string is annoying, the saddle groove is raised up a little farther than it should be IMO. Has anyone ever had an issue like this? If so, what did you do about it?
