capacitors

Okay so I've got this OLD Ibanez GIO 7-string and it needs a lot of work. Like, $300 to $400 worth of work. I'm starting with the pick ups and wiring at the moment. I need to know a few things and the one topic I found that explained a few things, didn't really help beyond helping me understand...

Hey guys, I am thinking about getting some Black Hawks for my Carvin Dc700, but I don't know wether to go for the ceramic or alnico V? She has a Koa Body, 5 piece Koa Mahogany neck. I also currently have EMG707s in it what pots / capacitor would be recommended? Should I buy the BKP Jensen 550k...
