Is it possible for someone to actually make a passive bass active? If it is what would be the process to do that? What preamps and electronics would I use (brand-wise)? I currently have an American Fender FSR Hot Rod Jazz. It has s-1 switching if that changes anything else. Please guys I love active tone, but i'm not sure if i have enough money to drop on an american deluxe jazz which would be the active bass of choice. Thanks!!!!
