Hello. I want to know if the alnico magnets used in regular stratocaster type single coils are the same used in jazz basses single coils. I have some alnico 3 magnets in different lengths that I never used on any strat pickup as planned, but I´m thinking in trying them in a bridge jazz bass pickup that I would like experiment with the sound. In width they seems to be the same, doesn´t no about the lenght yet. Also is viable to remove a magnet from a winded pickup and replace it without damage? It seems that with plastic coils, like the ones on the american standard series, have the wire around the plastic, while the vintage ones have the wire direct around the magnets, and they are what secure the top and the lower base in place. I think it´s not possible with those vintage types. Thanks.
