I am soliciting opinions on my next gear purchase. Given this gear, AKG Solid Tube, KM-184, M-Box, into a Power Book G4 with and external firewire harddrive attached, what would be my next best and most logical purchase? I am using this gear to record acoustic guitar, mandolin, fiiddle, bass, banjo and vocal. I am thinking along the lines of owning one or two Avalon 737sp's and an M149 or 147. My specific question is would I be better off getting a good pre first and then down the road pick up another mic or the other way around.
