Keyboard instruments from J.C. NEUPERT are supplied with wooden jacks (for historical models) or with plastic jacks in the well known rectangular shape. Both types are characterized by their easy adjustment, absolute reliability and low noise level. Wooden jacks without means of adjustment assistance can also be supplied upon request.
J.C. NEUPERT is able to offer a wide range of instruments and will assist you to find your own hand-crafted instrument. You may rent our instruments for only a concert or for longer periods. On request we also organize the instrument's transport. Please ask for an individual offer.
We are making historical instruments to enjoy playing it and not to tinker around.
Which type of instrument one prefers, historical or 20th-century, remains an individual decision.
Many good reasons to join a NEUPERT-harpsichord
Furthermore we made some modifications on our historical copys, to make them most reliable and playable, without falsify the character of the instruments. If the former harpsichord makers had the possibility to get adjusting screws in large numbers, they would have also used them for their instruments.
Here are some specifications about historical NEUPERT-harpsichords:
- The case is completely made of solid limewood, bonded in high quality timber joints.
- The wood for the soundboard comes from Ceresa, Italy, a very famous company for soundboard spruce.
- We have- because of our experiences- different thicknesses of the soundboard and only polish it with wood shavings to get the best effect of pulsating the tone wood.
- The jack-slides are made of lime wood covered with leather stripes, every wooden jack was fit in one by one and you have the most silent way to lead the jacks.
- The jacks are equipped with several regulation-screws, so they are very easy to handle and every technician has no problem to regulate the harpsichord.
- You can very easy remove the upper manual if there is a problem with the keyboard.
- There are adjusting screws for the keyboard for a simple and fast damper regulation.
- We use modern tuning pins in a layer-wrestplank for a equal and easy tuning.
- You can easily transpose the keyboard from 440 Hz to 415 Hz.
- The lid hinges have removable pins, so it's very easy to remove the lid.
- We use a splitted topstick to fix the lid in two positions.
- The usual stand (after Louis XIV) is very fast and easy to remove, there are only 3 screws which fixes the stand, but we may offer different kinds of stands too.
- The registers are easy to turn on or off with the metal levers above the keyboard.
- The guarantee for our instruments is five years for all defects in material or workmanship excluding costs of shipping or travelling.
NEUPERT-plucked keyboard instruments are supplied with wooden jacks (all models in historical construction) or with plastic jacks in the classic rectangular shape. Both types of jacks are characterized by easy adjustability, absolute reliability and low noise. On request, the wooden jacks may be done without regulation screws.
Normally we use Delrin quills, a plastic material, in its soundgenerating properties closely to the raven quill of historical instruments. Delrin quills guarantee a long durability. On request, your instrument can also be equipped with raven quills or with leather plectra, producing a soft and warm sound.
The construction of the instruments depends in a specific way on the individual national schools and epochs. The variety of construction principles entails different sound colours, closely related to the respective music literature. A certain autonomy claim the harpsichord reconstructions of the 20th century, which don't be related to any historical proto type. These models (Couperin, Cristofori, Bach) are characterized among others by numerous possibilities of registration and by technical equipment like pedals to operate the registers. Their sound is „authentic“ at least for the contemporary harpsichord music. Which model you prefer remains after all your personal decision. NEUPERT considers it as its responsibility to present a rich palette of different models and to advise you in selecting your custom-made instrument.
