Electric instrument music control device with magnetic displacement sensors
First Claim
1. An electric instrument music control device for use with an electric guitar, the device comprising:
- a foot pedal comprising an input jack, an output jack, a base portion and a treadle, wherein the treadle moves with respect to the base portion;
an electric guitar coupled to the pedal through the input jack, wherein the electric guitar supplies a high impedance audio output through the input jack to form an audio input signal;
an amplifier coupled to the foot pedal through the output jack, wherein the output jack supplies an audio output signal to the amplifier;
a magnetic displacement sensor coupled to the base portion; and
a magnet coupled to the treadle, wherein;
the magnet is located adjacent the magnetic displacement sensor to place the magnetic displacement sensor in a field-saturated mode, wherein the magnet moves with respect to the magnetic displacement sensor in response to movement of the treadle with respect to the base portion to modify the audio input signal to generate the audio output signal, and wherein the audio output signal from the field-saturated mode magnetic displacement sensor varies proportionally to the direction of the magnetic flux passing over the sensor; and
a volume of the electric guitar emitted through the amplifier is modified in response to moving the magnet with respect to the magnetic displacement sensor and varying the audio output signal delivered to the amplifier from the output jack of the foot pedal.

Abstract
An electric instrument music control device is provided having a foot pedal. The foot pedal includes a base portion and a treadle, wherein the treadle moves with respect to the base portion. The device further has a magnetic displacement sensor coupled to the base portion and a magnet coupled to the treadle. The magnet is located adjacent the magnetic displacement sensor to place the sensor in a field-saturated mode, wherein the magnet moves with respect to the magnetic displacement sensor in response to movement of the treadle with respect to the base portion. A sound characteristic of the electric instrument is modified in response to moving the magnet with respect to the magnetic displacement sensor.
