On a related note, I've never found the contemporary JBs' treble to be problematic, personally. My hot take, I suppose, is that if anything, the treble is pretty rolled off if you start comparing to the Custom, Custom 5, Distortion, Nazgul, Dimebucker, '59B, WLH, PG, etc., and like 80-90% of the Duncan humbucker lineup. So I don't think a little extra treble from the polished magnet in contemporary JB's is that attrocious of a thing.
