I've got this very nice early 50's Fender Deluxe 6, and the trapezoid pickup is not firmly mounted to the baseplate. It wants to tilt a bit away from the neck end. How are these fastened? How can I secure it? Thanks,
Brad

Its been awhile, but remove the two screws with the locking washers and move the pickup to the desired place sort of shimmy it a bit until you find the pickup sits straight. this is not uncommon.Try it, I think it will work. I have at times shimmed the base plate with a thin piece of sheet metal. Try it. |

I assume you mean the entire unit ... not the internal "pole piecless bobbin" sitting between the upper and lower casing.Here are the instructions I send to folks who what their Trap magnets remaged ... it will explain how everything is set up. quote:
Take the strings off ... and unscrew all the screws holding the tailplate/pickup assembly . GENTLY pull the entire unit up ... there should be significant slack in the ground/hot wires to look under and work. Basically there are 3 parts ... the cover plates (upper and lower), the DELICATE cardboard/fiber/waxed bobbin, and the two magnets. The wires run out a hole in the bottom cover plate to the pots/etc. These won't be monkey-ed with. On either end of the bottom plate you will see two nuts. Unscrew them (the bolt is welded to the upper plate and runs thru the magnets.) Once the nuts are off ... set the whole unit back down ... and then pull off the top cover plate ... SLOWLY and gently ... in case there is some wax adhereing to the bobbin. DON'T TUG ... it should lift off easily ... maybe a little wiggle. Once the top plate is off , you will see the two alnico magnets ... a big one on the bass side and a smaller one on the treble side ... and the coil
Tighteneing down those two nuts ... under the bottom cover ... will probably reset your unit ... Don't "hammer' them though ... snapping the welded screws ... bad news ... If that doesn't do it ... theres a few more tricks ... but I bettcha thats what it needs. And while you have it apart ... I'd be happy to remag them for you (and b0b  ) ... I haven't met a set yet that didn't enjoy a good jolt. ------------------

I soaked two sets in a glass of Jolt Cola. I couldn't tell any difference. |

I think you should just sell me the guitar cause I could use that pickup for my '52 custom 2x6  |

Thanks for the advice on this one guys. Actually, from what I can tell with the strings still on there, it looks as though the studs that come down from the top trapezoid thru the plate may have been broken off where there should be threads and nuts to hold it to the plate. There is enough stud left to align the pickup in the two holes, but they only stick thru about 1/8" of an inch. I can kind of tilt the pickup and pop it out of the mounting holes. I may need to find some way to secure it better since it seems that the threaded parts that held the nuts are gone. It actually works ok right now but it doesn't take much force to tilt the pickup toward the tailpiece. The sad thing is that this guitar is beautiful as is the case. It could be in a museum. Near mint condition. I'll try to post some pictures soon. It's actually my wife's guitar and it's one of those pry it from her cold, dead hands kind of pieces. Sorry Loni So how important is re-gaussing the magnets? It sounds great, but I have nothing to compare it to. I have a pickup rewinding friend here in town and he's got one of those giant horseshoe magnets for remagnetizing old pickups. He's also got a precise gauss meter so he can individually calibrate each pole if he wants to. Is this something he could easily do? Are the magnets the two grainy silver looking pieces sandwiched between the top and bottom trapezoids? Thanks,

If you take the strings off ... and disassemble the unit ... you can have a machine shop add the needed length on, to be able to secure it down correctly. You want it stationary ... You would only need to take the top plate with the welded on bolts to the shop. A less "professional way" ... would to epoxy it down. It could ultimately be pulled off if needed ... and the residual epoxy removed ... to return it to "original". Whichever fits your needs ... And yes ... remag it. quote:

There are no poles ... The magnets are the two blocks you described. Have your friend stick his probe ...  ... directly on the surfaces ... basically in the middle of the oriented surface ... then move it to the edges. He should get 600-700 gauss or so in the middle ... raising up to 800-900+ at the corners (edges). Your friends maggin' set up ... needs to be able to generate flux densitys close to these values ... Each oriented side needs to read approximately the same ... only the sign (+/-) being opposite ... You want the flux density associated with the top plate ... to be equal and opposite to the bottom plate. ------------------
