Conversion kit for 15-bar Autoharp. Includes all holders, springs, pre-felted bars, and buttons. Installation instructions, written by our repair shop staff, are now included. Chords are Bb, C, D, Eb, F, & G major; A7, C7, D7, E7, F7, G7; Am, Dm, Gm. NOTE: This may not perfectly replace your old chord bar assembly. There are known spacing issues with older autoharps, which can usually be worked around. The chord bar holders may need to be repositioned and some felts trimmed so the felts line up properly. Drilling new screw holes in your autoharp may be required.
