Abstract: The present invention relates to a novel device and related method for a musician, performer in a band, or an ensemble, to stop, shut-off and/or disengage the signals created by their instrument electronically through grounding or disconnecting the instrument's connection to an audio generation device such as an amplifier, speaker, or other digital interface. The invention is exemplified by reference to an electric guitar connected to an amplifier, with the control device disrupting the electrical connection therebetween and incorporating a guitar pic for the control of the connection disruption. The control device may be implemented either by grounding the connection between the instrument or by disconnecting it completely using an electrical switch.

Abstract: Various embodiments of subsurface support devices, interior underpin brackets, and systems and methods for elevating a settled or settling structure are disclosed. One embodiment comprises an interior underpin bracket. One such bracket comprises: a support shaft having a bore adapted to receive an underpin pipe; and at least two support arms pivotally fixed to the support shaft, the support arms adjustable between a retracted position in which the support arms are disposed parallel to the support shaft and an extended position in which the support arms are disposed perpendicular to the support shaft.
