7,285,714 Pickup for digital guitar
  Issued: October 23, 2007
  Filed: September 9, 2005
  U.S. Class: 84/726
Abstract:  A reluctance pickup for a guitar including a pair of magnetic pole pieces disposed within wire coils. The coils are oppositely wound and wired in series. Each pole piece has an elongated magnetic pole end extending above its respective coil. The pole pieces are disposed so as to form a pickup face having two approximately parallel elongated pole ends. The elongated pole ends have opposite magnetic polarities and create a magnetic field therebetween. The pickup is mounted beneath a magnetically permeable string such that a projection of the string intersects the pole ends at a selected orientation angle between approximately 28 degrees and approximately 58 degrees, preferably, 43 degrees, so as to optimize selected performance parameters of the pickup, including: channel-to-channel separation, frequency response, and dynamic response.
