The harpsichords Jan Kalsbeek builds are chosen because he found the originals appealing. When starting out, he only made French harpsichords. As an experiment he built an instrument after Mietke, which was so well received that this has become his main build of instrument. But he also makes other types of harpsichord, which may be seen under the heading of instruments in the menu.
The standard version of the instruments include: transposition, a simple stand with four turned legs, music desk, ebony naturals and bone topped sharps (unless stated otherwise), and a tuning hammer. All instruments have wooden jacks from Adam Swainson and are strung in wire from Stephen Birkett.
