I have a bass with the EMGHZ pickups. While for the most part I've been able to coax some decent sound out of them, I am thinking I might want to get something with a little more throaty mids and umph. (very technical description I know) Is it possible to just get a set of Nordstrand Big Blades or something else (maybe Delanos), and put those in? The bass has two batteries, (18V total). I don't want to spring for a whole new electronics set yet.
