The J.A. Custom Chord 48 Top of the line Harmonica has incredible response and tone. It features the most extensive and advanced reed work possible. Every single reed is attached using screws, yes you read right! All 384 reeds! Every reed responds to the same small air pressure and the tuning lasts much longer than on a stock harmonica. It has an enourmous volume and response. The comb is laser engraved with the customers initials.
