I'm interested to know how you decide what goes into or is left out of a relatively inexpensive harp. There are some design issues especially regarding the amount of pressure on the soundboard and therefore the construction of the harp to withstand that pressure. The Harpsicle seems to be made of plywood so nice looking wood has been replaced, but the soundboard would still need to be spruce or something like it which is thin and flexible but strong.
Inquiring minds (well one, anyway) would like to know.
