Chromonica 270 Top of the line

The J.A. Custom Chromonica 270 Top of the line has incredible response and tone. It features the most extensive and advanced reed work possible. Every reed responds to the same small air pressure and the tuning lasts much longer than on a stock harmonica.

The slide and mouthpiece is upgraded to a 3 part mechanism, which gives the player much better response and dynamics. The harmonica is assembled with screws instead of nails for easier maintenance. The valves are modified for a much smoother action.



Reed Plate

All valves and reeds are removed, the underside of the reeds and the reed plates are then flat sanded. Reed slots are modified and every reed is re-attached using screws.
