Okay; I looked around but found nothing really specific on this topic, so here goes. Can I, (and I'll use my bass specifically as the example), install a preamp in my Warwick Fortress to change my bass from passive to active? (I'm assuming that anything can be done; just wondering how.) So; how complicated is it, and is there a specific brand, style, etc of preamp that is recommended? Would it behoove me to have a tech do it to make sure it's done right? I'm noobee to this aspect of the whole thing.
