Crazy Idea About Pickup Magnets


Daniel Sorbera

Recommended Posts

i think you are referring to a brass baseplate. by adding a bar magnet under a singlecoil's pole magnets, you will actually demagnetize the pickup. not a very good idea.

Not if you don't put "like" poles together. I think this will indeed add to the magnetic field's strength and thus the output. I'm trying toget the parts to build a gaussmeter and this is one thing I want to test...

I know little about this type of thing, but as it was said, like charges repel(opposites attract) so unless your gonna be taping or somehow forcing the magnet onto the back of the single-coil, than it's not gonna work.

If you wanted to make the magnets stronger inside the pickups could you not use NdFeB (Neodymium Iron Boron) magnets that are supposedly about 7 times stronger than AlNiCo..

I've been meaning to ask about this any way, but has any one ever amde a pickup using these things?

I know fishman makes a acoustic humbucker using that magnet. HEy the magnet on my pickups is on the bottom(like I can see the whole thing, it's just glued on the pickup)could I just pop that one off and put a new one in? And if I can do you know where I can buy a Neodymium (I know it's a compound but they call them "Neodymium " magnets) magnet? I know I can get this one from stewmac but it's not a Neodymium. Do you think a Alnico 5 magnet would be somewhat like a neo? I have been thinking about EMG active pickups. How do yuo think there "vintage" models compare to "real" single coils?

lol I just read over that and man thats a lot of questions :D

I've seen that done with cheap single-coils, a bar magnet beneath the poles. It has to be one of the poles directly beneath or on the side. That will probably saturate the bottom part of the coil with magnetism, I don't know about the rest. It will also make it more linear output-wise because there is a more uniform magnetic field acrossed the coil.

Here's an idea, Nd 38 magnets can be used to recharge alnico magnets, right? how about putting 6 individual circular ones on the bottom of the poles. Super AlNiCo! B):D Seriously though, someone's gotta try this! I don't use any alnico single coils myself, sorry. I'm addicted to humbuckers, especially now that I know how to build preamps allowing me to get just as much note definition while retaining it's wider harmonic spectrum.

I have some N-Dym mags. I use a 3"x1/4"x1/2" block for charging alnico poles, and I have a bunch of small 1/16" and 1/8" discs for - you guessed it - putting underneath alnico poles to increase output. I want to do this for my middle single coil because it gets in my way, so i want to screw it WAY down. So far from the strings, the added magnetic pull shouldn't give me the "stratitis" effect, and I need more output. I got mine from www.wondermagnets.com

I tried the 1/16" ones and they seemed to add some output. They really add output when stuck on the TOP of the poles, but then they pull on the string. I want to measure the increase here, which is one reason I want to build a gaussmeter. I didn't try the 1/8" ones because they have a greater diameter and once down in the pickup, I don't think I'll get them back out! My singles are the top half of Ibanez C2s - like a DiMarzio HS2 stacked single.

You CAN'T use a block underneath the pickup. It is just too strong.

But I want to measure this stuff. Like, does Alnico "conduct" magnetism the way steel poles do (which would lead to large increase when a ceramic or Ndym mag is beneath the pup) or does it kinda "replace" the field of the lower mag with its own magnetism? Would humbucker steel poles that were milled to have a flat spot where the magnet contacted them conduct more magnetism to the strings, since the contact area is greater?

I could play in my basement with a gaussmeter and some mags & pups for hours...

There is a pickup that uses n-dym - the q-tuner. http://www.q-tuner.com/ Note that the magnets are pretty small. And Fender uses samarium cobalt in their new Lawrence designed noiseless pickups.

six of these in a single coil sound nice.

In answer to the original posters question you can do what you are suggesting but you will need some different magnets.

Cheaper single coils have a ceramic bar magnet attached to the six steel poles. You could replace this with an alnico magnet but not a standard humbucker type. The magnet needs to have it's poles on the 7mm x 63mm face, a standard humbucker magnet is magnetised so that the 2mm x 63mm face on the side is the pole. It would work, just not very well.

ok I think I got it now. Can I buy 5 (5 is all that will fit under a single coil) of these. Those are Neodymium. There used to charge alnico magnets. Could I just pop off my magnet now and put these little guys on? If so how do they need to go on? do they need to want to stick or want to repulse? Or does it matter cuse theres no other magnets on anyway? Also If I just did this to the middle pickup would it effect the other pickups because the magnetic pull is sooo strong????
