Unfortunately for you, a drummer made it in first. Allow me to ramble without merit ....
The G bugles have a brighter, more direct sound than the B-flat brass instruments. In the hands of a very good brass section, it's a very in-your-face sound. Unfortunately, they're (I guess) harder to play in tune, because most of the time they could be considered assault weapons. Personally, I like the warmer sound of B-flat instruments, but for someone who came to drum corps before the change, it just doesn't sound right.
How's that, actual brass guys?
