About moving the band to the middle of the student section, 50 yard line, for this exact same problem. Before they were relegated to a corner and could not hear. That move helped. And someone on either ramblings or this board wa in the band and made it happen.
We are back to the same issue. Except now we have a special section designed just for the band. Ugh - not a placement that makes it easy to hear without a mic.
If we are not able to mic: try band in the south stands, like UCB does, to see if crowd can hear them. If that doesn’t work, middle of student section might be sorth a try.
The band is a big part of game day. Should be heard easily!!
