摘要： An elongated string support for a stringed musical instrument includes a neck having a heel portion, a head portion, and a finger-board portion extending axially between the heel portion and the head portion. The finger-board portion has a spiral profile from the heel portion to the head portion. The elongated string support also includes a finger-board attached to the neck and having a heel end and a nut end. The finger-board has a spiral profile from the heel end to the nut end. The neck and the finger-board are zero degrees from a heel thereof and to a predetermined angle greater than zero degrees at a nut thereof.

摘要： An electromagnetic pickup for use in sensing the mechanical motion of strings includes a ferromagnetic housing of elongate, longitudinally recessed form in which a ferromagnetic core is received. The core includes a plurality of coplanar, spaced, finger-like projections directed at the walls of the recess. Both the walls of the recess and the finger-like projections of the core are permanently magnetized to a common magnetic polarity and thus will concentrate by magnetic repulsion the flux into the gap between the projections. A coil wound around the core then senses the flux changes of these concentrated flux fields due to string motion.
摘要翻译：用于感测弦的机械运动的电磁拾音器包括细长纵向凹陷形式的铁磁壳体，其中容纳有铁磁芯。芯部包括指向凹部的壁的多个共面的，间隔开的指状的突出部。凹槽的壁和芯的指状突起被永久地磁化成共同的磁极性，并且因此将通过将助焊剂的磁力排斥到突起之间的间隙中来集中。缠绕在芯上的线圈然后感测由于弦运动而导致的这些集中磁通场的磁通变化。
