We offer four levels of High End J.A. Harmonicas, which are the most responsive of the J.A. Harmonicas line, in part because of the performance comb. The High End Basic and Advanced levels of customization feature the performance comb and intensive reed work that corresponds to a player’s technique and style—tone and use of bends and overbends, in particular. The High End Master level of customization features the performance comb, chromatic-capable reed work, and, for the H-E Marine Band Master, cover plate modification and optimization. Custom cases are available and other options are available.
