I have a question TB, i currently use .136-.102-.076-.057-.041 circle k strings on my 5 str basses. Lately i've been wanting to try a .142-.106-.079-.059-.043. set. My question is; would i have to widen the nut to fit the 142? i do not want to widen any of my basses nuts. hopefully some experience to chime in. thanks in advance.
