How To Make Cheap Guitar Pickups Sound Great for Less Than $1 (Ceramic to Neodymium)
I personally think this is bullshit. There’s not much difference in sound between different type of magnet used. So going from ceramic to neodymium is I think useless… Anyway. I publish this video to give you another point of view. There are lots of myth in music like tonewood, a difference of sound between mylar film and an oil filled capacitor, ect. This one is another crap that is popular. So if you want to lose time and money, and possibly ruin a set of pickups, go for it.
This is a complete tutorial on how to replace a guitar pickup’s ceramic bar magnet with neodymium disc magnets. Neodymium magnets are very powerful and only one thin disc is needed for each pole piece. The neodymium magnets used in this video are 5mm in diameter with 1mm thickness. Thicker magnets can be used for more magnetic power but the same higher magnetic power can be obtained by stacking thin magnets. Stacking thin magnets also has the advantage of giving greater flexibility in adjusting magnetic strength.
It is important to closely match the diameter of the magnet to the diameter of the pole pieces. Using a 6mm diameter magnet on a 5mm diameter pole piece would not be efficient. Likewise, using a 5mm diameter magnet on a 6mm diameter pole piece would also be inefficient.
