yes you need to have a controller to be able to use the mic. (you can use the mic on Guitar Hero 4 and upwards)
You can`t... Since the Plug in for the Guitar hero Mic is a USB and the Controller is way different from a USB Plug in.
Mic- PS3 Controller & mic Guitar- PS3 Guitar Bass- PS3 Guitar Drums- Ps3 Drums JA
Xbox360: Plug the mic into one of the USB ports in the xbox and turn on a controller. Use this controller to join, pick your rocker etc. and then just use the mic to sing.
No, you can use the guitar hero 3 controller, which is wireless, for guitar hero two
No, you have to have the headset that plugs into controller or the wireless one you can purchase...
no
no, you can use a controller.
yes
Yes.
no
I don't believe you can use the PS3 Guitar Hero controller on the PC to play anything
That completely depends. Is the guitar hero 3 controller for the same platform as the guitar hero 2 controller ? (I.e. xbox 360 or ps2)
