These shots highlight an area of rehersal concern. The circle on the ground dictates where our singer locates during rehersal. While the cloud will obviously make an improvement on gain before feedback, the new diffusion behind him is a concern.
I've decided to hang a blanket from the back edge of the ductwork encasement that we will roll down during rehersal to kill some highend.
While tracking I will roll up the blanket and fasten it in the ceiling drop corner. The cotton mass in the corner may actually work at a bit of trapping device as well.
(You can see a bit of real life detail of this area, in the finished bass trap photo... (post #22) it is the same corner.)
