Given the number of folks that have swapped the original MM for something 'after-market', there must be plenty here that have the original MM units gathering dust around the place. If I was stateside I would offer you mine, although it is '91.
Personally I prefer the transparency, punch, and definition of the ceramic over anything AlNiCo so I can't imagine really wanting to put the original pickup back in. Here's a few seconds of the Delano MC 4 FE with EB Cobalt Flats and John East 3-band:
I have an issue with the 2 Band EQ Om my 2002 EBMM Stingray
With Treble boosted it hums.
I don’t want to change anything about this lovely instrument but have to get this fixed.
