[78-L] stylus for vertical-cut Edisons

[Mike Daley]

I'm looking into converting a Stanton 500 cartridge to play Edison
Diamond Discs. The Esoteric Sound website seems to suggest that a
regular 3.0 stylus (which I already have) will work fine.

I know about reversing the polarity of the cartridge (though I don't
yet know how to do it!)
Don't vertical-cut records require a completely different stylus? Any
suggestions would be much appreciated.
