Hard Tops are available only on Bettis cymbals.
With Hard Tops, I work-harden the top of the cymbal more than normal. This extra hardening increases the stick sound for better articulation. I forge Hard Tops into shape, and place every hammer strike on the top surface of the cymbal instead of the customary mix of top and bottom strikes.
If having a lot of stick is your thing, then Bettis Hard Tops are just for you.
