Tim warned me against a Cold Sweat in a Basswood guitar with a maple fretboard, I don't think ebony is different enough to change that opinion.
Interesting.....maybe Tim Might chip in & explain?
Tim explained it to me something like this: The fret is set in very hard wood (maple in my case, ebony in yours) and this gives a fast transient attack to the note, combined with the EQ and ceramic magnet will not be a pleasant combination. He recommended either something Alnico (Holy Diver for example) or a hotter ceramic such as a Miracle Man or Painkiller.
