The A parts are the modded 990 with the two inner layers of screen removed. The B parts are the stock 990. They were placed on a stereo bar as close to coincident as I could get them, and angled in slightly so they were pointed at the same fret on my guitar, sitting about 12" out from the upper bout. They went through my Rane preamp and direct into my Digi002 for a/d conversion. No post processing. My playing is somewhat lackluster, but I feel like it gives enough of an example of what the mics sound like.
