Abstract : The string motion of the solid body electric guitar is captured by an electromagnetic transducer sending an electrical signal to an amplification system, providing the sound to be perceived. Transducer and amplification have been so far well investigated, but the vibrational aspect of the instrument in connection with lutherie has been rarely considered. The aim of the present study is to analyse mechanically and perceptually the own influence of a single construction parameter on the vibrational behaviour of the whole instrument and on the perceived sound. Nine guitars, whose single difference is the neck-to-body junction, were made specially for this study: three necks are screwed to the body, three are glued and three guitars have a neck-through construction. The guitars have been studied using vibro-acoustical methods: modal analysis and conductance measurements at the frets and at the bridge. They have been then played by twenty-two professionnal guitarists along with semi-directed interviews. As expected, we could not observe no greater differences in the modal behaviours between two different constructions neck junction than between two identical constructions. However a pyscholinguistic analysis of the interviews shows that the musicians discriminate more subtle differences between the guitars.
