The 12-hole Marine Band 364 is ideal for the player who wants more range than a 10-holer provides. This harp has been customized with a $35 comb made by Andrew Zajac which secures the reeds plates with screws instead of nails. Therefore, this harp is more airtight and much easier to clean than the original. Note that the C gives you extra notes on the low end and the G gives you extra on the high end. Includes original box. The harp has been cleaned, tuned and tested by AlbertHarp. See video for more.
