 Though the construction of a double top significantly differs from the traditional soundboard, a double top guitar often looks just like a traditional guitar.A thin soundboard is often incorporated and used to obtain the most vibration and to allow for optimal sound.While some people are positive towards innovations that directly affect a guitar's loudness, prefer the full round bodied tone, change in tone that can come with it (if done well), and feel that the loudness of some of these guitars (in particular Smallman guitars) is a by-product of their musical qualities rather than an end in itself; there are also a number of people who are generally critical of the tonal qualities of these guitars; why should guitar makers devote so much time in producing loud guitars with a thin sound, when the vast majority of guitarists do not need an exceptionally loud guitars?
