My friend said to put a new capacitor in my basses for more midrange and sustain. Does he mean on actives or is he just blowing words out his a**? (He's known for this kinda stuff, he's an avid squier basher to boot. Too bad me + my squier VM jazz sounds 10x better than him with a ric. All in the hands, baby!) Anyway, where would I put it on a passive if this is true?
