a fraction of the time required to assemble conventional guitars further the resulting guitar will not differ substantially either in appearance or acoustic properties from guitars manufactured in accordance with conventional techniques using the acoustic support structure of the present invention also reduces the skill level required of the workers in assembling the guitar prior to assembly the soundboard support structure 130 and the back support structure are formed by injection molding the side portions soundboard and back portions of the guitar are then cut for assembly unlike conventional guitar manufacture where the support structure can be modified slightly to accommodate discrepancies in the dimensions of the soundboard side portions and back portions of a guitar in the assembly of a guitar according to the present invention the soundboard side portions and back portions should be cut to substantially the same measurement as the acoustic support structure referring to fig8 there is illustrated in an exploded clam shell view an acoustic support structure according to a second preferred embodiment of the invention the acoustic support structure comprises a soundboard support structure 130 u2032 and a back support structure 150 u2032 the soundboard outline is shown in dotted lines and is exploded upwards from the soundboard support structure 130 u2032 the outline of the back.
