Aight, so I tried it and AIYAIYAI
it didn't sound good..
well I shouldn't say that
it wasn't the SOUND I was looking for
Basically I took the snare and walked around the stairwell
up top, midway, down below
and the echo was just bouncing around all over the place
that it was really drowning out the drum tone
so I tried a different room where the walls are about 8' high (but higher with above the acoustic paneling, or dropped ceiling) with the length at about 45' long and 25' wide, windows on 1 side and drywall on the other; carpeted floors.
I just kind of plucked myself into a corner and started playing, and it sounded surprisingly good. But it may all go to hell depending on mic placement, but I just wanted to give you an update on the whole stairwell thing.
Thanks for all your input thus far!
