GUITAR PICKUP MAGNETS!!!!

[jimbo1986]

I am building pickups for my fender guitar and I am using AlNiCo 5 magnets that are all the same strenght. My problem is that the low "E" (first string) is louder than the high "E" (sixth string). Does anyone know how to solve this problem so that all the strings have equal levels. Changing the magnets strenght is not a problem for me but I don't know how much each string needs changing. Is there is a scale, etc...?

thanks

The standard solution to this problem is to adjust the distance between the magnet and the strings.

believe it is more common to adjust the diameter of the pole pieces under the string, but it still does not answer the "by how much" without a trial and error approach, or adjustable shunts of some sort.

Dangelop has the right idea here, as can be noticed by looking at other pickups. Some have all the pole pieces the same height, while others have staggered pole hieghts. To vary the diameter of the pole pieces MAY do something (who knows what?) the easiest way to do that would be to make several different bobbins with different sized poles. To make something that would be easy to change sleeves and pole pieces would be a bit of work. Also, some guitars wouldn't leave much room for this as the string spacing may be narrower than other guitars.

BTW, if anyone has any information on where/whom to purchase material to make the bobbins from, I'd appreciate the info. Thanks.

always remember the sensitivity of the magnet differs because of size of your strings the low e is a large string and the high e is smaller therefore it creates less current there for less volume. they are all right in that you need to move them closer for each string or use slightly stronger mags for each (though moving them closer is much easier) or if each coil is amplified seperate then you can just change the gain on each to compensate for the difference in sensitivity. tho i think you should just angle the whole thing up a bit to find the sweet spot for the high e and im sure it will make a,d,g,b all sound much stronger also.

Make sure the pole pieces are adjustable.
