So he's looking for "Guitarist, Drummer, Bassiest and Keyboardist" which suggests that he's a singer.
Then he adds, "If you have any microphones for gigs that is a plus." So I guess he doesn't have his own.
But he follows that with "You must have your own gear." Which is nice.
Probably best not ask if he has a PA.
