The INTERNALLY INTEGRATED DIGITALLY AMPLIFIED ELECTRONIC GUITAR adds new minuature digial technology to standard electric guitars by utilizing various integrated circuits inside the body of the invention to replace the standard external devices standard electric guitars require in order to operate. The external devices the standard electric guitar requires to operate are: (1)-interface cable, (2)-audio amplifier, (3 )- speakers) and (4)-speaker cabinet. With standard electric guitars a magnetic coil pickup (or pickups) captures the magnetic flux created by the guitar strings vibrating and carries that signal through a series of tone controls through an I/O connect or or out-put jack on the external side of the body of the guitar. An interface cable is then required to be inserted into the guitar at one end and the other end of the interface cable is then inserted into the I/O connector or input jack of an external audio amplifier (powered by AC or DC current) where the signal is boosted and routed to output speakers (which may require or not another separated I/O connection ) between the amplifier and the speaker. With the INTERNALLY INTEGRATED DIGITALLY AMPLIFIED ELECTRONIC GUITAR all components required for operation are contained within the guitar. The signal passes from the vibration of the strings to a Hex Magnetic or piezo electric MIDI Pickup and is converted from a anlogue signal to digital information. The digital information is then manipulated by internal tone controls via a MIDI (music instrument digital interface) synthesizer and sent to the internal Digital Amplifier which boosts the signal and creates either a mono or stereo output path whic h connects directly to the systems internal set of Digital Speakers. Due the extreme minuaturization of the IC components the entire system can operate on DC current provided by on-board rechargable batteries. The INTERNALLY INTEGRATED DIGITALLY AMPLIFIED ELECTRONIC GUITAR offers significant advantages over the standard electric guitar. It is portable and requires non of the external devices that a standard electric guitar does in order to operat e. The INTERNALLY INTEGRATED DIGITALLY AMPLIFIED ELECTRONIC GUITAR can operate anywhere without the need for an external AC power source. The INTERNALLY INTEGRATED DIGITALLY AMPLIFIED ELECTRONIC GUITAR DC power cells c an be conveniently recharged with it's on-board charging system and the Digital Amplifier and Digital Speaker system draws less electrical power and delivers superior sound quality over conventional solid state or I C analogue amplifier/speaker combinations. With the on-board MP3 player/recorder; the musician can record the output of the guitar listen to it later and/or accompany the output of the MP3 player by playing the guitar as the MP3 player replicates what is stored on it's hard drive.
