The little black knob on the treble corner is actually the allen fine tuner wrench held in place by a magnet. It came as a keychain tool with the Daigle fine tuners. I cut it off and painted it. It is very handy and accessible amid all the picks and playing paraphernalia.
This autoharp is fitted with an extra back called a resonator. It makes the harp louder and more resonant by allowing the instrument’s own back to vibrate freely. It adds only a half inch of thickness to the autoharp so it still fits in the case.
This resonator is a unique innovation of my own in that it is also an attached stand. I fitted it with a little flipper like a picture frame and grip holes so it is easy to set the autoharp aside when performing or jamming. The resonator is attached to the autoharp with velcro so it is easy to remove and reattach.
