"Special ZR Tremolo"

[kadeks]

I was looking at the Ibanez S470DXQM and it says that it has a "special ZR tremolo" and has a "Zero Point Tremolo" instead of a ZR tremolo. Can anyone tell me what this is all about? What's so special about it, and is it any good?

Thanks.

Look for the coupon in your next box of crackerjacks.
