| 20090080677 | Stringed instrument with simulator preamplifier - A stringed instrument and preamplifier combination where the preamplifier simulates the sound of analog tube amplifiers, and contains only solid state active devices. The preamplifier uses a diode branch with the diode biased into its forward active region and as a non-linear resistive element to provide signal-modulated gain on the operational amplifier gain stage. An alternative embodiment supplements the diode branch with series and parallel resistors as additional design optimization parameters. Another alternative embodiment adds symmetrical output clipping diodes to simulate a vacuum tube push-pull output independently of the diode branch. | 03-26-2009 |
| 20090268927 | Fuse - The invention fuse is a new type of guitar amplifier. This new amp allows for digital chips to be plugged into the amp and to be played. The amp processes the digital chips and guitar player can play whatever is stored on digital chips. This allows for the buying of chips to play whatever is liked and the amp processes the digital chips that store the amp sounds when guitar is played. The digital chips store sounds that are plugged into the amp. | 10-29-2009 |

| 20110033066 | Circular speaker - A device comprising a circular shaped resonating chamber having an upper resonating chamber and a lower resonating chamber, which are joined together by a sound board, the sound board divides said upper resonating chamber and said lower resonating chamber, wherein one or more speakers are mounted to the sound board, the sound board has one or more breather holes, the upper resonating chamber has one or more exit holes for the sound to escape, and a base member for holding the circular shaped resonating chamber, the base member is a guitar amplifier, and the resonating chamber allows the sound waves to travel from the speaker to resonate sound into the sound board and out through the circular shaped structured walls outward in a 360 degree radius. | 02-10-2011 |
| 20110211713 | ATTACHABLE GUITAR AMPLIFIER AND EFFECTS APPARATUS - A combination pickup, multi-effects processor and amplifying apparatus that is attachable, and detachable to an acoustical guitar and does enable a player of an acoustic guitar to produce, modify and amplify a myriad of sounds, and tones that are normally associated with that of an electrical guitar. The apparatus performs these functions while remaining an independent self-contained accessory that can be easily attached to, and detached from, an acoustic guitar with minimal intrusion to the body structure, appearance, and acoustical properties of the guitar | 09-01-2011 |
| 20120328128 | METHOD FOR ARTIFICIALLY REPRODUCING AN OUTPUT SIGNAL OF A NON-LINEAR TIME INVARIANT SYSTEM - A method for artificially reproducing an output signal of a non-linear time invariant system includes the steps of inserting an input signal of exponential sine sweep type in the non-linear time invariant system, acquiring an output signal of the non-linear time invariant system corresponding to the input signal, obtaining a mathematical function that characterizes the non-linear time invariant system on the basis of the output signal and applying the mathematical function to a further signal to obtain a still further signal which reproduces the output signal that would be obtained from the non-linear time invariant system if it were driven by the further signal. | 12-27-2012 |
| 20130136278 | GUITAR AMPLIFIER - A device and methods are provided for a guitar amplifier. In one embodiment, an amplifier includes an overdrive shaping circuit including one or more elements for harmonic shaping of a received signal. The amplifier may also include a power amplifier circuit configured to receive the harmonic shaped signal from the overdrive shaping circuit, wherein the power amplifier circuit includes a switchmode amplifier to amplify the harmonic shaped signal includes one or more elements to increase the output impedance of the switchmode amplifier. An output of the amplifier can output a signal with desired harmonic shaping and a dynamic response. | 05-30-2013 |
| 20130177174 | PERCUSSION INSTRUMENT - A percussion instrument is provided. The percussion instrument having: a seat; a pair of sidewalls extending downwardly from the seat towards a bottom of the percussion instrument, each of the pair of sidewalls providing a first tone when contacted; a forward surface extending from the seat and located between the pair of sidewalls, the forward surface providing a second tone when contacted, the second tone being higher than the first tone. | 07-11-2013 |
| 20140219477 | GUITAR AMPLIFIER - A system and method for a guitar amplifier that overcomes the disadvantages of known amplified speaker enclosures and circuits while providing more effective volume control. A venue switch selects different output ranges for the guitar amplifier. Volume control still adjusts output regardless of venue switch position. In the low-output setting for the venue switch a house or other quiet venue is accommodated with the guitar amplifier that can work in larger venues in the high-output setting. | 08-07-2014 |
| 20140254833 | PORTABLE ISOLATION CABINET - A portable isolation cabinet includes a body with a sidewall, a floor, and a positioning device. The sidewall is located on an edge of the floor. The positioning device is disposed on an interior face of the sidewall for removably securing a combination amplifier. The lid is pivotally connected to the body along one of its edges lid and an edge of the sidewall. The insulation is located on the interior face of the sidewall and is operable to absorb, and prevent reflection of, sound. The body and the lid are operable to close and thereby form an enclosed interior space. A focuser reflects sound emanating from the amplifier and directs it to a microphone. | 09-11-2014 |
| 20150049883 | AMPLIFIER - An amplifier, such as a vacuum tube guitar amplifier, including a configurable preamplifier, power amplifier and/or power supply. Configuration of sections of the amplifier can be controlled by software, which can be updated directly on the amplifier though an editing interface, by downloading new configuration data from an external device or network, or by updating hardware-based cards or daughter-boards. The amplifier can store multiple circuit designs, and give users access to designs on demand, along with associated potentiometer and switch settings stored in ‘patches’, as well as allow real-time control over potentiometer settings via the amplifier's user interface, or external control via a communications interface. Global settings can also be configured to take into account factors such as type and rating of vacuum tubes. The same methodology can be applied to stand-alone preamplifiers or power amplifiers, solid state amplifiers, preamplifiers or power amplifiers. | 02-19-2015 |
