The last one I did, we got a whopping $18 at the scrapyard for the harp. It looked better as a piece of art leaning against the front of the store than some of the modern art we have around town - several customers said so... Get a heavy duty pair of leather gloves and break each treble and tenor string by over-tuning with a tuning hammer. Then cut each bass string or unstring them. Do this while the harp is still attached or it can be catastrophic. Aside from the wood and parts value, it can be a heck of a lot of fun. Remember that each treble string is two notes and needs only to broken on one end. Cut the other one off after the tension is released. A 1/4 size socket stuck backwards in a drill makes a quick and easy tuning pin remover.
