Physical Modelling of Musical Instruments has become one of the major fields when research concentrates on properties important for musical performance or instrument building (Bader & Hansen 2008). It has been applied to many instruments. With guitars it could be found, that the coupling of bending and in-plane waves in the guitar body plays a crucial role in the sound (Bader 2005a) (Bader 2005b). Also the need to build the guitar back plate under tension to enhance the sounds' brightness could be shown. When systematic changes are applied to the thickness of top plate, back plates, and rims, fan bracing, and ribs, the change in brightness of the sound radiated from the different parts do sometimes show a linear but mostly a nonlinear behaviour, caused by the complex coupling of the parts.
