[quote name='The Mana Knight']Is the mic with Rock Band USB? If it is, it should work. Well, I was able to play KR on my PS3 with my USB headset on a 20GB (same as 60GB). If it's bluetooth, it will not work. I'll investigate though.[/quote]
Yeah that's what I thought too, but for some reason when I connect my Rock Band Mic via USB, KR doesn't recognize it for some reason. Can you please try with your Rock Band mic if you have Rock Band and let me know?
