Hello guys and gals. I just recently was given an old Squirt Jaguar. It does not have the Duncan designed pickups. Since I already have a my primary bass, I've decided to make this my project bass. Ive decided the pickups will be my first mod. I do not want active pickups. I am not totally against having pickups with an active preamp, that is if someone could explain the difference between active pickups and an active preamp. Could someone also explain what in the hell that active "tone" or bass boost knob is on this jaguar would greatly be appreciated! I also don't want to spend over 200 on the pickups. I thought the new EMG Geezer B's sounded pretty good. I never particularly liked the sound of EMG's, but they did have a nice vintage sound that I like. Thank y'all.
