Does anyone know if there's a place I can find settings for the BR-864 to make the effects sound like certain guitar players' set ups?

I'm interested in getting my guitar to sound like Dimebag Darrell's (R.I.P.) because my band is covering some Pantera stuff, but I can't quite get it and there are so many settings in the BR-864 that I'm getting tired of guessing.

I'd also be interested in getting some stuff to sound like Slayer, and CKY. I really dig the sound those guys get out of their equipment and just can't seem to get very close.

And, if not for the BR-864, is there any programmable effects pedal out there that caters to this kind of request? (ie has a place to look up settings to mimic certain band sounds.)
