So I got a 1995 Japanese made Marcus Miller Jazz the other day and I love it. Except.. I am missing the tone knob in passive mode. So I did some research on here looking to see if I could add one to the bass and came across someone who had switched the two volume (chrome) knobs out with two stacked knobs like the '62 reissue jazz bass. My questions are, would this solve my need for tone control in passive mode? And if so, how can this be done? I am COMPLETELY new to wiring and I'll probably need a lot of help, but that's why I turned to this great community! Any more input it greatly appreciated. Thanks!
