Unique playable guitar made from mixed material (denim - jeans ,burlap,paper ....) except the fingerboard....(wood)..... All this violins is the first i make and is a prototype. Is a full playable ...but have 1 or 2 small problem in some points. For this reason this violins is only for the exhibition and shows and not for a sold. If someone wants to buy one, would I make a new similar in appearance but not the same . All the instruments is unique. If someone wants something special, can send me and the material that wants to build a musical instrument.
