I found the hair scrunchies and tried them out as a mute for the dulcimer. It worked great. It stopped a lot of the ringing and, unlike the cardboard, had a clear tone. The closer I slid it up toward the frets, the more it muted but didn't changed the tuning.
Now I have a pickup to make it louder and and mute to make it softer, for practice.
Still waiting for the bass mute.
