Jen,I know you can order strings for all brands of harps, and also for non-brands if you give them the specifications from Mountain Glenn Harps.
This was cut from a message by Glenn Hill on the harplist about replacing strings on Pakistani harps: e-mail Laurie Hill at mwstrings@aol.com, to get more info on replacement string sets for harps.
My harp was made from a Markwood kit, designed by Mark Bolles who worked out a string/harp design process. He then sold the harp kit and harp making side of his business to the Hills.
