custom covers and combs

i have seen websites that offer custom covers and combs. They say they fit common harmonicas like the Hohner special 20 but doesn’t that effect the way it sounds?

they offer brass-different woods-acrylic- and other kinds of combs.

the Covers are powder covered.

Is it a Good idea? It would be cool to have a custom color.

you are correct, covers and combs do change tone. A good example would be the hohnerms harps. they all use the same reedplates but the differand covers andcombs means the way the play and soud is dramatically different from one model to the next. trying a set of custome covers isnt a badidea but i would start with 1 set and if you like it then look at getting them for othe harps
