If you want to have the chance to build the guitar (or bass) of your dreams with your own tow hands, this is the place. Founded in 1988 , Eki Hoffmann is the "alma mater" of this unusual fun corner in Sant Ferran. Students in groups of maximum 6 people will get their own instrument within 18 days.  A workshop in Formentera Guitars is a unique opportunity for guitar fans and an unforgettable experience.
