Abstract
Abstract A musical instrument which has a guitar, radio and microphone connected to a source of electrical energy and to a single amplifier. The main body of the guitar is hollow having a battery pack and radio mounted therein. A microphone is mounted to the main body of the guitar and is connected to the battery pack and to the amplifier of the radio. Means are mounted to the main body beneath the guitar strings for producing audio electrical signals in proportion to the sounds generated by the strings. The means are connected to the radio amplifier. Switches are mounted to the main body and are connected to the radio, microphone and means for allowing the musician to selectively connect the microphone, guitar and radio together for producing a combined sound through the radio speaker or alternatively for operating only the microphone or the microphone and guitar.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
207 words
A musical instrument comprising: a guitar having a hollow main body forming a sound box with a long neck attached thereto and strings with opposite ends attached to said neck and said main body; a battery holder mounted within said main body for receiving at least one battery, said holder having electrical output terminals contactable with said battery for providing electrical energy; a radio receiving set mounted within said main body and connected to said terminals for the operation of said set, said radio receiving set including antenna means, an audio speaker and a first amplifier; a microphone mounted to said guitar and being electrically connected to said terminals, said microphone having an output line connected to said amplifier; first means mounted to said main body beneath said strings being electrically connected to sAid terminals and said amplifier and being operable to produce audio electrical signals in proportion to sounds generated by said strings; and, switch means mounted to said guitar and connected between said amplifier and said antenna means, between said amplifier and said microphone and between said amplifier and said first means, said switch means being operable to control electrical signal flow from said antenna means, said microphone and said first means to said amplifier.
Claim 2
Dependent Claim
207 words
A musical instrument comprising: a guitar having a hollow main body forming a sound box with a long neck attached thereto and strings with opposite ends attached to said neck and said main body; a battery holder mounted within said main body for receiving at least one battery, said holder having electrical output terminals contactable with said battery for providing electrical energy; a radio receiving set mounted within said main body and connected to said terminals for the operation of said set, said radio receiving set including antenna means, an audio speaker and a first amplifier; a microphone mounted to said guitar and being electrically connected to said terminals, said microphone having an output line connected to said amplifier; first means mounted to said main body beneath said strings being electrically connected to sAid terminals and said amplifier and being operable to produce audio electrical signals in proportion to sounds generated by said strings; and, switch means mounted to said guitar and connected between said amplifier and said antenna means, between said amplifier and said microphone and between said amplifier and said first means, said switch means being operable to control electrical signal flow from said antenna means, said microphone and said first means to said amplifier.
Claim 3
Dependent Claim
41 words
