of Stringing Schedules
Wolfgang Zuckerman's design for a small harpsichord was so popular when it was introduced in the early 1960's that he could not keep up with the demand. When a customer asked if he could buy the parts and put it together himself, the harpsichord kit was born. Approximately 15,000 Z-box kits were sold. In addition to the thousands of owner-built Z-boxes scattered around the world, many other early revival builders, such as Sperrhake, Wittmayer, Neupert, LeSage and Albarda, used similar dimensions and scaling for their small instruments.

*strings, keys and jacks are traditionally counted from the left (lowest note), although stringing schedules traditionally list wire from the highest note to the lowest, probably because most builders string the treble first. It is confusing, I know; sorry.
