Tonala skillnader mellan två gitarrer med olika kroppstjocklek

As a guitarbuilder it is an advantage if you can control and understand what is creating the character of the tone. To approach this vast jungle of variables that controls the tone in a guitar, I built two guitars and in one, guitar 2, reduced the thickness of soundboard, back and sides.
The purpose was to compare the guitars and establish if there was a significant difference and what it was, in the guitars ability to produce sound. The thought was also to try the thesis: loud but short, long but moderate tone. Also if a lighter built guitar has an advantage in producing a loud but short ton and vice versa.
The instruments has been examined by five guitarist, one guitarbuilder and a professor in Speech, music and hearing at KTH in Stockholm.
The relative obvious conclusion is that guitar 2 is a bit louder and has a clearer base and treble but the more part of the guitarists fancied guitar 1 better. This one has got more mass fore the tone to stay alive with. A lot of guitarists wish is to get louder instruments but if you ad one thing and are forced to lose another the guitarist will not be happy anyway. To provision the musician one ought to leave the bodymass alone and see to that the instrument responds sufficiently fast. Clear is also that the lack of a large number referenceguitars limits the results.
One further conclusion is that the test: loud but short, long but moderate tone is correct. This thesis is directly bound to the two tested guitars.
