Blue Moon Aluminum Combs are CNC Milled from Aircraft Grade (6061) Aluminum. They are tumbled to remove the sharp edges and burrs and then anodized to seal the aluminum. Anodizing is a process of adding a natural oxide layer on the metal which increases the corrosion and wear resistance.

The Hohner MS-Series family of harmonicas includes such popular models as:

• Blues Harp
• Big River
• Meisterklasse
• Blue Midnight
• Pro Harp
• Cross Harp
• Deuce and a Quarter

Our MS-Series combs will fit them all. Our MS-Series Combs have five screw holes with which to fasten the reed plates. All MS-Series reed plates have five screw holes, however most of the stock MS Combs have only two or three holes. The additional screws help build more airtight harps. The stock screw on a MS harp is a 1.6mm. Just let us know if you need a couple and we will include them at no additional charge.
