The Twelve-string Guitar has twice as many strings as a standard acoustic guitar. The strings can be picked in pairs using a six-string technique, or they can be strummed. The guitar produces a loud, full-bodied sound with a bright shimmering tone, used to great effect in pop songs, blues and folk ballads.
