Thanks to everyone for the help. I'm going to be referring to this thread for a long time for tips for my wife who is just getting started with the 'harp.
Thanks. I have place a bid on an autoharp at Ebay. I'm scared, but the feedback on the seller was very positive. If it can be tuned I will be happy.
'Catspaw49, do I remember seeing somewhere that you build autoharps?
