So later today ill be the owner of a used Ibanez GSR200. Want to do a re-fin and possibly new pickups and electronics. Im buying it to have a mod bass, since ill be getting it for a decent price. Problem is, ive never owned an active bass. I dont know what to look for when searching for pickups. Do I have to look for soley active pickups or are passive/active pickups all the same and its all in the preamp electronics?
