We have the rock band 3 drum kit and guitar. Bought for the Xbox 360. We got rid of the x box ages ago so my question is can the instruments be used on a PS3? With the PS3 disc of course
I want to say no, since they're likely branded for Xbox 360, have the 360 buttons and system button, etc. But I could be wrong.– nightsurferAug 30, 2016 at 17:19
From some quick Google searching, there are a few sources that come up with bad news:
Unfortunately, no, 360-branded Rockband instruments will not be compatible with a Playstation 3. This extends to the PS3 copy of Rockband. Furthermore, an adapter for this kind of deal does not exist either.
Sources here and here (to confirm the opposite direction as well).
