1939 Rickenbacher B-6 lap steel.
Magnet:
the wide chrome part with the middle gap/slot is the magnet, right? It should attract an iron or steel item? My magnet does not attract anything made of iron or steel. Can it be remagnetized?
Tone knob:
the guitar tone does not change when the tone pot knob is turned (left knob in pic below). Could the tone knob not work because the magnet is not magnetized? Or the tone pot itself is bad, or the capacitor is bad? How do I check this out?
The volume knob works fine (right knob in pic below).
I saw this somewhere:
"Some pickup designs used magnets that were not made of a permanent magnetic alloy. A prime example is the Rickenbacker horseshoe pickup. These magnets – which are the “horseshoes” themselves – often go dead or “almost” dead. Once they lose their magnetic charge to a sufficient degree, the result will be a loss of output and frequency response".

Do most electric guitar techs/repairmen know how to remagnetize a pickup?
I mean is this a standard procedure that has to be performed on guitar pickups?

Guitar techs would send this to a pickup house... Lollar does them, I assume there are others.
It is quite common for Ricks to need this, the horseshoe magnets were not made of any especially super material (like alnico or ferrite), just iron.

| How much the horseshoes are suppose to be magnetize? I mean the chrome part of the pickups of my DC-16 are just subtly attract a dime, it is correct? The sound is strong and nice but did they are suppose to be strongly magnetic, like for exemple a dime will stay glue on them? |

Jon,
Get in touch with Rick Aiello through the forum. He's the expert on these pickups and can get them working as new. I don't want to make any promises for Rick, but he has been very generous with me and others in remagnetizing these pickups. Thanks, Rick!
Also, if your tone control seems to act more like a volume then you may have a damaged coil as well. It can be tested with a meter at the jack, or of course at the coil itself if you have it out of the instrument. Good luck, hope you get it all sorted out. |

Oh, you had me worried. *All* coins are non-magnetic, completely... except for US WWII pennies (1943?).
Use a proper piece of iron or non-stainless steel, like a nail. Test it with a magnet, then test your pickup magnet. Perhaps it has more magnetism than you thought!

| Ouff! Thanks Stephen, I tried with a nail and my pickup are strongly magnetic! This steel sound very very nice, I now have a Deluxe34 rack for that I like a lot. |

Thanks for all the info folks.
Took the 1938 Rickenbacher B-6 to local guitar shop, B-6 fixed plays great!
