Devices for making a floating trem a dive only?

[IBANEZRGONFIRE]

Is there any devices i can buy to make my edge trem dive only like EVH ?
the floating trem is to much a PITA to deal with and i like to use drop D tuning

you can get a tremol-no at www.allparts.com for $65. i use that and also a hipshot tremsetter with all my d-tunas. works great. they are about $40 and will you'll still be able to pull up, but when you drop "d", everything won't go sharp.
