All things Cigar Box Guitars, Instruments, Players, Music, Techniques, Festivals, Resources, and More! What is a cigar box guitar?, Simply put, it's a stringed instrument that uses an empty cigar box as it's resonator. They are not necessarily of the same design as a normal 6-string acoustic guitar. For example, some cigar box guitars have only 1 or 2 strings. Many do not have frets up the neck, but are played fretless or with a slide. Visit http://cigarboxguitars.com
