The dual keyboard sustain pedal stabilizer is designed for use with a pair of keyboard sustain foot pedals. The dual keyboard sustain pedal stabilizer comprises a stabilizer base, a first pedal-retention area in cooperative engagement with the stabilizer base, a second pedal-retention area in cooperative engagement with the stabilizer base, and an underside of the stabilizer base having a non-slip surface. The first and second pedal-retention areas each include retaining structures proximate to the stabilizer base. The retaining structures enable secure retention of the keyboard sustain foot pedals within the pedal retention area. The dual keyboard sustain pedal stabilizer provides stable footing for the musician on damp floors for both feet while providing a dual keyboard sustain pedal stabilizer that stabilizes either one or two keyboard sustain foot pedals. The dual keyboard sustain pedal stabilizer has no moving parts and is compatible with essentially any keyboard sustain foot pedal.

An apparatus and method for providing a musical instrument effects unit with transistor bias voltage visualization are disclosed. An example embodiment includes a musical instrument effects apparatus with transistor bias voltage visualization, the apparatus comprising: a transistor amplifier; a bias control coupled to the transistor amplifier to adjust an active bias voltage setting for the transistor amplifier; and a bias voltage meter coupled to the transistor amplifier to monitor, measure, and enable visualization of the active bias voltage setting, the bias voltage meter including a visualization device to produce a visual representation of the active bias voltage setting.

A spontaneous audio tone inducing system, machine, and method of use.

A modular mounting system may include multiple parts couplable together to form a customizable assembly of parts. The parts may have a variety of lengths, depths, and heights and a rectangular prism shape or a rectangular wedge shape. A first part may have a first set of coupling holes on a first side surface for aligning with a second set of coupling holes on a second side surface of a second part. The first part may have a first cable routing opening for aligning with a second cable routing opening of the second part. The second part may couple to the first part at a front position and a third part may couple to the first part in a rear position and adjacent to the second part. Additional parts (e.g., a fourth part, a fifth part, etc.) may couple to the first part, the second part, and/or the third part.

Provided are a control device, a control method and a control system. In a control system, a headphone and a pedal device are in communication with each other through first communication, and the pedal device and a portable terminal are in communication with each other through second communication. Accordingly, even when the headphone can be connected to only one control device, a control instruction from the pedal device can be transmitted to the headphone through the first communication, and a control instruction from the portable terminal can be transmitted to the headphone through the second communication and the first communication.

A specialized audio/instrument cable with built-in digital signal processing capabilities that adds digital audio sampling capabilities that allows the user to trigger synthesized sounds or virtual musical instruments from within the cable itself to affect the sound generated from an instrument or microphone such that the cable is the only connection needed between the instrument or microphone and an output device. Using voice recognition, the specialized cable can select an audio effects chain algorithm and/or sampled sound algorithm extrapolated from a musical digital audio fingerprint (MDAF) created from a desired musician's instrument to alter the sound of the input instrument's audio.

Rather than a vertical see-saw type of volume pedal for a guitar, a foot-controlled volume pedal for a guitar has a foot pad that swivels in a generally horizontal arc around a pivot point. The foot pad has a pointer at its far end (away from the pivot point) that points to the volume numbers 0-10. The player's heel will generally be over, or close to, the pivot point, and the foot covers the pad or part of the pad. The pivot point comprises a rotatable shaft that is coupled to a smaller rotatable shaft of a conventional potentiometer, by friction, gears, or a belt, for controlling the volume into the guitar amplifier. The rotation ratio of the two shafts may be, for example, 6:1. The swivel arc may be large (e.g., 5-8 inches) so a precise volume can be set between 0-10.

Battery powered devices are provided with electrically isolated outputs. One exemplary battery device comprises at least one battery; and control electronics configured to provide a plurality of outputs from one of the at least one battery, wherein the plurality of outputs comprise at least one output that is electrically isolated from at least one other output of the plurality of outputs that each provide power to one or more of a plurality of loads. In another exemplary battery device, the control electronics are configured to provide a plurality of outputs from one of the at least one battery, and further comprises a housing assembly comprising (i) at least two surfaces, wherein the at least two surfaces have a space therebetween configured to house the control electronics and the at least one battery; or (ii) a tubular structure configured to house the control electronics and the at least one battery.

A pedal device receives a connection signal transmitted from headphone to establish first communication that is communication with the headphone. Then, in a case where the first communication has been established, the pedal device transmits the connection signal including information indicating that communication with the headphone has been established. By receiving the connection signal from the pedal device, a portable terminal establishes second communication that is communication with the pedal device. In a case where the received connection signal includes information that the communication with the headphone has been established, the portable terminal may determine that communication establishment between the pedal device and the headphone has been completed.

A system and method for providing variable power is disclosed. The system includes a power supply which provides power to at least one instrument. A pedal comprises a variable resistor that is configured to produce a resistance value within a predetermined range based on an amount of pressure which is being applied to the pedal. The voltage being supplied to the instrument is varied in accordance with the resistance value produced at the pedal.
