What can You do with an electronic device You don't like (mosly because of its battery consumption)?
Remove and form a secondary soundhole...
Initially the edge of the original hole wwas a lot more uneven than what You see now. As the sound was a bit booming i reduced the size of the hole (which means tuning the resonance of the body deeper). Now it is ok and i can hear me pretty loud. Let's see how my bandmates will respond. I cannot test how this has changed the sound in the far field.
