Honestly, this video is an hidden ad, and I don't care because their idea is so awesome ! I don't really believe that was possible to craft a paperboard guitar before this video of Signal Snowboard. All of the conception is very clever and atrocious, I never believed they can put the strings and stretch them. At the end you can see a few guitarists of the fender workshops play with and they are surprised by the excellent results ! The sound is good.
