A member of the Echo Octave series, this model features a wood body which adds resonance to the rich octave tuning. Open backed covers amplify and project the sound out to the audience, and the curved mouthpiece makes the high and low notes easy to reach. Octave harmonicas are similar to Tremolo models in reed layout and musical range. Instead of having reeds tuned to the same note, however, each double hole has one reed tuned an octave apart from the other. The resulting sound is stronger and full bodied, but without the tremolo effect. This is the harmonica equivalent of a twelve-string guitar and is ideal for regional and international styles like Cajun, Old-Time and Irish music.
