Hey guys (posting after a long time)

I am absolutely clueless about this so please help me out.

1) Where can I buy guitar, microphone and drums for Rock Band (PS3), do you have any idea if its even available in Dhaka ?

2) How does the mic in the ps3 work ? Does a normal USB headset with microphone work or does PS3 have any special/strange requirements ?

As you have probably guessed, its not for me, I am getting this as a gift for someone. The game itself has already been purchased and I will search the usual shops tomorrow for the guitar, drums and mic.. any suggestions as to which is the best console shop will be very helpful.

Best wishes !
