Blend and configuration control for a string instrument

摘要

A blend and configuration control for a string instrument connects to a pair of pickup sensors located on the string instrument and in one arrangement includes a pair of potentiometers mechanically coupled for concurrent mechanical travel to provide individual pickup sensor output selection and parallel blending of the outputs of the two sensors. A switch is also included to immediately and reversibly provide a series configuration of the two pickup sensors. In another arrangement, the blend and configuration control includes a pair of potentiometers mechanically coupled for concurrent mechanical travel to provide individual pickup sensor output selection, a series configuration of the two pickup sensors and series blending of the two pickup sensors.

主权项

1. A blend and configuration control for a string instrument having a pair of pickup transducers, comprising:
a switch having multiple poles coupled to the pair of pickup transducers; and a pair of potentiometers each being coupled to said switch, each of said pair of potentiometers having a displaceable contact, said pair of potentiometers being mechanically coupled to one another for concurrent mechanical travel of said displaceable contacts thereof; responsive to said switch being in a first position:
said pair of potentiometers providing selective operative coupling of (a) one of the pair of pickup transducers to said pair of output terminals exclusive of the other of the pair of pickup transducers, or (b) the other of said pair of pickup transducers to said pair of output terminals exclusive of the one pickup transducer, or (c) the pair of pickup transducers connected in parallel, one with respect to the other, to said output terminals, the output of each of the pair of pickup transducers being variably blended responsive to a position of said displaceable contacts exclusive of opposing ends of said mechanical travel; responsive to said switch being in a second position:
the pair of pickup transducers being connected in series relationship irrespective of a position of said displaceable contacts of pair of potentiometers.
