For the past few months I've been leading worship at a Bible study in the chapel at a retirement residence.
The chapel is small, but the acoustics (or lack thereof) produce echos and amplify all sounds. I first began using my mando, but soon realized that it was just too loud, so I switched to ukelele.
I finally occurred to me to mute my mando. I took off the tone-gard and slipped my little Gold Tone brass mute on the bridge. Voila, a more respectable volume that better lends itself to the situation.
