Abstract
Devices and methods for transducing vibrations of a ferromagnetic string in a musical stringed instrument are provided. Specifically, including those for modulating the timbre of a stringed musical instrument with an electromagnetic pickup independent of loudness, sensitivity and dynamic range.
Claims20
A method of modulating timbre in an electromagnetic pickup device for a stringed musical instrument having at least one ferromagnetic string and a fixed distance from the at least one string, comprising:
- (a) providing an electromagnetic pickup comprising a first bobbin operably coupled to the instrument disposed proximate and below the strings and a first coil wrapped around the body of said first bobbin;
- a first selectively movable magnetic device for generating a magnetic field around the first bobbin;
- and a selectively movable magnetic flux conductor extending through the bobbin, disposed above the selectively movable first magnetic device, and defining an adjustable gap, the gap configured to be adjusted independently of the distance between the magnetic flux conductor and the at least one string;
- (b) positioning the first selectively movable magnetic flux conductor at a predetermined distance below the at least one string;
- and
- (c) modulating timbre by adjusting the gap between the magnetic flux conductor and the magnetic device without changing the distance between the first magnetic flux conductor and the at least one string.
