The Bolton jack,
(see price list)
the all-important item in many kits, is available separately. It is used on a regular basis by professional makers who like it for its high performance, reliability and user-friendliness.
It is of the same weight as a traditional wooden jack, but has the advantage of full adjustability and freedom from swelling in damp weather. Its dimensions match those of several other popular types and it can therefore be considered as a replacement for older types of plastic jack which may have started to fail, or simply as an upgrade.
The jacks are of very smooth plastic to give a
lightning-quick, reliable action.
Besides top and bottom adjusting screws, one of the user-friendly features is the easily removable tongue which makes it much easier to get at the root of the plectrum to voice it.
1970s Zuckerman harpsichords are among those which may benefit from replacement of the jacks. Bolton jacks ae the same thickness as Zuckermann jacks of that period, so it is a simple job to modify these harpsichords to accept Bolton Jacks.
Other components offered are shown in the price list.
The plectra are of the pre-voiced type, as used in the kits. Although more expensive then plain plectra, the extra cost is not a significant factor in the total instrument price and is fully justified by the time saved and the better chance of a good result for the amateur.
