Well, I'm going to have to operate on my Fender Marcus Miller Signature Jazz Bass due to the incompentecy of the music store I bought it from... So I need all the expertise of knowledgable music store employees and ...well really really smart people! There is a peculiar buzzing, not the 60 cycle hum that is "standard" with J-p/ups, but a loud buzzing...when I place my hand on my bridge, it seems to ground it out (correct term?), but not so much when I mute the strings...so it's not the p/ups, right? Did Fender forget to add that bridge grounding wire? Do I need to switch the wire placement around on my active passive switch? (I read that, when wired properly, sounds like a '78 Jazz and a Marcus Miller...) Whoever would know, please help! A Bass is a horrible thing to waste! Thanks a lot!
