While the bright and soaring harmonics of this instrument are its undoubted trademark, that doesn’t mean you can’t achieve incredibly exciting sonic effects an octave below. Enter the Rocket Low harmonica from Hohner. Perfect for low drones and harmonica bass lines, the Rocket Low comes specifically tuned an entire octave down and exudes a deeper, thicker, and more growling musicality than traditionally tuned harmonicas. An exceptional fit for blues, country, rock, solo work, and beyond, the Rocket Low sets the mood with a low-end authority that will captivate onstage and light up the ears of listeners on record. To fit a wide variety of applications, the Rocket Low is available in six different major keys, including low C, D, Eb, E, F, and F#.
