Chromonica 270 Master

The J.A. Custom Chromonica 270 Master has excellent response and tone. Out-of-the-box chromatics are well known to have response issues on hole 10, 11, and 12, but on the Master model all holes and reeds are fully playable with equal response.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.
