Hello. I have a bass that I like a lot, but I cant seem to get action at a reasonable "lowness". I like action a little higher than normal, But on this bass the action is just too high at higher frets. I tightened the trussroad and lowered the saddles, it is still high over 12th fret, and buzzes like hell on first ones. Is the neck just unmanageable? How would you know that for sure? Maybe put a business card into heel joint? Opinions? Tnxkbai!
