I'm looking to change out the stock pickups that came with my KSD704J. I'm looking for the absolute growliest, dirtiest, most aggressive, edgy, sizzling J pickups out there. Can you please make a recommendation, and tell me why you recommend that one. Try to be as specific as possible, such as a certain model from the company you recommend. I'm not too sure if ceramic or alnico is more aggressive sounding, but whichever you recommend, please give a brief commentary as to why. Thanks to all in advance.
