Hi everyone, I have a second hand F Bass BF6. It is a fantastic sounding bass and one I seriously think I could keep a lifetime. Unfortunately, it does have one problem. Some kind of Lindy Fralin humcancelling PU was dropped in the bridge position. It's an excellent pickup and I want to keep it. However, the neck PU is a single coil and I get the standard buzz when I turn it up regardless if the bridge PU is up or not. It's a great sound and matches well with the Fralin. I just want to get rid of the buzz. I had a tech look at the wiring and it looks fine. Any recommendations on getting rid of the hum? I know some Alembics do/did come with dummy pickups in them to cancel out any noise. Is there some way I could drop something in the electronics cavity? Suggestions please. Thanks, Eric.
