Abstract:
1. A variable tone configuration control for string instruments, comprising: a pair of pickup coils disposed on a string instrument for inducing voltages therein responsive to vibration of at least one string of the string instrument; and a pair of potentiometers each having a displaceable contact, said pair of potentiometers being mechanically coupled for concurrent mechanical travel of said displaceable contacts thereof, said pair of potentiometers being coupled to a pair of output terminals, and said pair of displaceable contacts being coupled to said pair of pickup coils, said pair of potentiometers providing selective operative coupling of said pair of pickup coils to said output terminals responsive to a position of said displaceable contacts, wherein said selective operative coupling includes (a) said pair of pickup coils being coupled in series to said output terminals, or (b) said pair of pickup coils being coupled in parallel to said output terminals, or (c) effectively coupling only one of said pair of pickup coils to said output terminals, said effectively coupling of only one of said pair of pickup coils to said output terminals being responsive to said displaceable contacts being positioned at an intermediate position of said mechanical travel thereof.
