HARMONICA MATERIALS AFFECT ON TONE- AN OPINION
I have been playing harp since 1969. Back then, the Marine band was it. Since then, I have tried a lot of the ever growing choices. I treated myself to a Joe Filisko solid brass Special 20 harp many years ago. That inspired me to try experimenting, assembling harps using different materials and designs, to see what I liked best.
I tried variations of materials for the combs and cover plates. The comb material had the biggest impact on the sound. I used combs from wood, plastic, aluminum, titanium, bamboo, composite, steel and brass. The SOLID brass combs (purchased from Tom Halchak
Blue moon harmonicas) sounded the best. They have a more pleasing tone, sounding fuller and have a louder acoustic volume. Please note, I am referring to the RECESSED version (for $64.95). This version is airtight, so you can play with minimal breath and increased nuance. Assembly is easy. First gap the reeds to your taste. Then drop the reed plates into the perfectly fitted inset. Now ENJOY! These are true lifetime instruments. I have been playing them for 8 years and HIGHLY RECOMMEND them.
You don’t have to take my word for how great these Combs are. You can try them yourself without any worry. Here is the guarantee from the website:

I have tried wood, plastic, silver, brass and chrome for the cover plates. None of the various materials improved the tone. In fact, the silver muffled the tone, in an unpleasant way.
There are, however, various processing enhancements for the stock cover plates. I have only tried the powder coated cover plates, from Blue Moon harmonicas. They seemed to make the tone clearer and are smooth on the lips. Also, they come in different colors, so it makes it easier to grab the right harp in a dark club. HIGHLY RECOMMEND!
