I don't post much, have lurked for years and bought a couple things from ILFers, but I need your help. My drag punk band Pussy Tuesday has 10 days to get all this shit together for a festival we're playing at The Smell in LA, and at a minimum I wanna have tapes to sell. I'm recording us live in our music room on an old Fostex 4 track: I DI my bass into one input, the singer gets another, and we have two left for the drums.
My bass is at GC getting set up, and I'm pickin it up in a couple hours. Unless anyone in greater LA sees this and wants to sell me something, I need to bite the bullet and buy mics there today, too. I was thinking a kick mic and an overhead made the most sense with just two inputs left, am I on the right track? What would be at GC that'd be good to get?
I just got a new credit card, so budget is open lol. However, I want something cheap and tough and faithful, but that I won't outgrow too quickly; whatever the kick and overhead equivalent of the SM57 might be. All I have right now are an SM58, 3 Behringer Ultravoice XM1800Ss, some Pyle PDMIK1s ($3.50 apiece on PartsExpress, holla), and, like, the mic that comes with Rock Band. Please help this lost little lamb.

PS: If anyone plays flute, I'm interested in buying a cheap one that isn't trash for my boyfriend for Valentine's tomorrow. What should I look for?
