It depends, if you are playing this on an early PS3 (20 or 60gb) which still contains the PS2 backwards compatibility, it might work. Otherwise it won't work on your PS3 and last I checked you can't use PS3 Guitar Hero controllers on a PS2, even though it has USB ports.
Unfortunately, no, a Rock Band guitar controller will not work for Guitar Hero games. However, a Guitar Hero guitar controller will work for Rock Band. You could also use the wire less Rock Band Guitar on Guitar Hero III: Legends of Rock
I've heard it will NOT work.
IT does for Guitar Hero 3, World Tour and Metallica. Not for Guitar Hero 2
Yes, starting with Guitar Hero: Aerosmith.
The 360 Xplorer guitar will only work on PS2 if you're playing Guitar Hero: Aerosmith or newer, and not with any Rock Band games.
Guitar Hero controllers work with all Guitar Hero games, which is great! WOO!
yes most guitar hero products work on other guitar hero games
No, you need a Guitar Hero guitar.
YES!!
Yes it should all guitar hero guitar controllers work with all guitar hero games and all Rock band games
It does work for other games, at least for 4 and 6, anyway.

Guitar Praise does not support peripheral devices from other games like Guitar Hero of Rock Band.
