at the risk of sounding like a complete moron, i'm going to post this question in hopes that i will finally have an answer. i've had this bass for about a year now.. nice well made, off-brand but very nice. It's got a passive p/j combination, very nice bass. then i sold my ibanez.. it sucked but that's besides the point. I need to know what each of the four knobs do (lol...) i'm lefty, so right handed they would look sort of like this: O O __O O i know that two are volume, one bass and one treble..all i know though is that i set it by ear, not having any idea which one is which. the controls aren't all that good, however. if they were, i'm sure i would have heard the differences by now. can anyone help me? i believe this is semi-standard, so maybe someone out there will know. (i'm almost positive that the top two are volume, but the question is raised which volume controls which pickup...) thanks.
