Abstract
Abstract An electric guitar is coupled through one channel of a stereo amplifier to a corresponding speaker in conventional manner while separate means responsive to string movements and pedal controls produce an organ like sound amplified in the other channel and reproduced in another speaker.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
244 words
In an electric guitar, having a microphone and controls therefor, producing simulated organ tones, comprising: first means, coupled to the microphone and controls, for amplifying the electrical signals produced by the; a first loudspeaker, coupled to said amplifying means, for audibly reproducing the electrical signals amplified by said amplifying means; a plurality of tone generating means, each associated with a corresponding guitar string and tuned to the frequency thereof, responsive to the engagement of the guitar strings by the frets of the guitar, for generating a plurality of simulated organ tones; second means, coupled to said plurality of tone generating means, for amplifying said plurality of simulated organ tones produced by said tone generating means; a second loudspeaker, coupled to said second amplifying means, for audibly reproducing said amplified simulated organ tones; a plurality of elongated strips of carbon material, each longitudinally disposed along the neck of the guitar below a corresponding guitar string, and positioned below and perpendicular to the frets of the guitar, said strips being coupled to said frets and said plurality of tone generating means so that the resistance of each of said strips varies with the position of the frets engaged by the guitar strings when finger pressure is applied to the strings of the guitar, for varying the output frequency of said plurality of tone generating means and the simulated organ tones produced; and means for coupling said plurality of tone generating means to said second amplifying means.
Claim 2
Dependent Claim
244 words
In an electric guitar, having a microphone and controls therefor, producing simulated organ tones, comprising: first means, coupled to the microphone and controls, for amplifying the electrical signals produced by the; a first loudspeaker, coupled to said amplifying means, for audibly reproducing the electrical signals amplified by said amplifying means; a plurality of tone generating means, each associated with a corresponding guitar string and tuned to the frequency thereof, responsive to the engagement of the guitar strings by the frets of the guitar, for generating a plurality of simulated organ tones; second means, coupled to said plurality of tone generating means, for amplifying said plurality of simulated organ tones produced by said tone generating means; a second loudspeaker, coupled to said second amplifying means, for audibly reproducing said amplified simulated organ tones; a plurality of elongated strips of carbon material, each longitudinally disposed along the neck of the guitar below a corresponding guitar string, and positioned below and perpendicular to the frets of the guitar, said strips being coupled to said frets and said plurality of tone generating means so that the resistance of each of said strips varies with the position of the frets engaged by the guitar strings when finger pressure is applied to the strings of the guitar, for varying the output frequency of said plurality of tone generating means and the simulated organ tones produced; and means for coupling said plurality of tone generating means to said second amplifying means.
Claim 3
Dependent Claim
79 words
The electric guitar as recited in claim 1, wherein said first and second amplifying means comprise a two-channel, stereophonic, electronic amplifier, having the first channel thereof coupled to the guitar and said first loudspeaker, and the second channel thereof coupled to said coupling means for said plurality of tone generating means and said second loudspeaker, so that said first loudspeaker audibly reproduces the sounds produced by the guitar strings and said second loudspeaker audibly reproduces said simulated organ tones.
Claim 4
Dependent Claim
49 words
The electric guitar as recited in claim 2, further comprising a plurality of manually operated switching means, each coupled to a corresponding one of said plurality of tone generating means and guitar strings, for switching said plurality of tone generating means on and off during operation of the guitar.
Claim 5
Dependent Claim
68 words
The electric guitar as recited in claim 3, further comprising a plurality of variable resistors, coupled to the strings of the guitar and said plurality of tone generating means, for varying the resistance between said tone generating means and the guitar strings, thereby adjusting the output frequency of said plurality of tone generating means and tuning said Plurality of tone generating means to the strings of the guitar.
