Re different harmonica materials: I have had bodies milled out of plastic,wood,and brass for my Meisterklasse chromatic in the hope of obtaining a richer or mellower sound than that obtained with the original aluminium body. The end result was that despite expecting to (and wanting to!) hear a difference the brass comb sounds exactly the same (to me) as the aluminium,and the wooden and plastic combs sound so similar to the aluminium that I'll admit that I'd probably fail a blindfold test to tell them apart.I'm not saying that there are absolutely no discernible differences with the wood or plastic substitutes,but to my ears they are so insignificant that I can find no acoustical advantages in substituting one material for another.Having said that,I can certainly hear considerable differences between different makes and models.An example that stand out is the comparative bright sound of Hering chromatics compared to their German counterparts,and the significant difference in the sound of the CX-12 from other Hohners. Last week I received a set of wooden coverplates from Bill Romel for my MK chromatic.Unlike the use of different body materials, the wooden cover plates make a very significant difference to the overall sound and performance of my instrument: . They reduce the volume I would achieve for the same amount of effort if I were using the regular coverplates, . They change the tone significantly to my ears.I don't know if mellow is quite the right word, it's like playing a solo chromatic recording through a graphic equaliser with the top 3 or 4 frequency controls adjusted to cut out those frequencies entirely. . While all the notes still respond satisfactorily with the wooden coverplates I find that the reeds seem to respond easier with the brass coverplates(this perception may be due to a combination of my first 2 observations). I want to make it crystal clear that these are only my observations and that that other players may have entirely different experiences with wooden coverplates than myself.I actually quite like them and rather than replacing my standard coverplates I'll use these(quite often I suspect) on a 2nd MK chromatic for their different sound as the situation requires.Bill has done a beautiful and professional job in making them and I would encourage anyone to try a set of these coverplates. Any suggestions as to why the Herings sound brighter than Hohners? Cheers, Paul
