The South German baroque instrument is made of walnut and decorated lavishly with ebonized ripple mouldings. It sits on an appropriate stand with a top and bottom frame and twist-turned legs. The action is based on a mechanism that can be found in an original 17th-century instrument made by Martin Kaiser, where the jacks are quarter-circular, providing all the advantages in touch and playability of a harpsichord. The keyboard is covered with ebony or ivory (optional).

The late medieval instrument is modelled on the original in the Royal College of Music, London − the earliest surviving stringed keyboard instrument. It is made of lime, gut strung, and, being a table instrument, it comes without a stand. The keyboard is covered with grained maple and bog oak.
