A recommended 10 hole pro model. The Hohner Marine Band is the original blues harmonica. Its pear wood comb and pinned cover plates have been standard issue for decades and its warm tone is behind many classic original blues and country recordings. Later Hohner models were developed from the Marine Band, which took its name from John Philip Sousa’s famous military ensembles. The channels are standard gauge, which promotes rapid movement around the instrument, while the standard harp size means easier use of hand effects. The Marine Band is supplied in all major keys.
