Since you have been so helpful with my bass B-Mac,maybe you can answer a question I have about the emg hz pickups. I have read several articles that state the hz's are a passive pickup,but the tone controls are active hence the 9v battery....what I'm confused about is should I engage the -15 db cut on my practice amp? Its an Ampeg BA-108, I ask because when I engage the switch the volume drops considerably but when I use my Mockingbird (also active) the volume is loud. So I guess what I'm really wondering is should I even engage the -15 db cut since the hz's aren't really an active pickup. Thanks for all your help, I really like my Dean and finally knowing what model it is really clears up a big mystery.
