Basement "live" recording: baffles, mic shrouds?

I'm in a band of basement heroes playing once a week and recording things "live" occassionally as we go. We're doing instrumental jazz & blues, with: - drums - bass - a guitarist playing a stereo guitar rig into 2 Princeton Reverbs blended with guitar synth into a small PA - a trumpet player who occasionally sings I'm using a Yamaha AW16G digital machine to record 8 mics at once with the room set up as shown here: Everything sounds pretty good, but I'm getting a lot more bass & guitar in the drum overhead condenser mics than I'd like. I'm thinking about trying 2 ideas, and would appreciate your thoughts: 1) buy the 2 inch thick 4 foot by 8 foot pink foam insulation boards I've added to my sketch to place on both sides of the drumkit, it hopes of blocking the direct blast to the drum overheads. I'd also move my 2 bass cabs back along the same wall to put them "around the corner" from the drumkit. 2) make up condenser mic "shrouds" out of 20 oz. styrofoam cups with a terri-cloth lining to make the mics more directional - about like this sketch: Would shallower cups be better (less depth, but still shrouding the rear & sides)? Any chance this will improve things, or will the bass & guitar notes just sneak around the corner into the drum mix anyway? Thanks, Cb

I'd fire the guitar and bass amps away from th drums and set it up like this. cheers john
