Last time this topic was being hashed over on harpL, a young lady 
friend of mine, a non-musician was at my house. I asked her to go 
sit in the other room. I played four different model  280's, three 
with plastic combs, one with a wood comb. Each time I played the 
one with the wood comb she said "that one sounds the best, it 
sounds little sweeter and has more character". I switched back and 
forth, tried to trick her but she was able to pick out the wood 
combed chromatic each time. The wood combed one is older, been 
played very little, and in great condition, but the other three are 
in tune and play great also. She also did think the other three all 
sounded the same.
So I don't know, was I inspired to play better knowing I was 
holding  a wood combed harmonica? I doubt it, I'm cosistently 
mediocre. Maybe someone more knowledgable will tell me these older 
ones were better built or had better reeds, that could be.  Before 
reading these discussions on harpL I had always believed I could 
hear a difference, now I'm uncertain.  I find it difficult to 
believe that there wouldn't be an audible difference, when every 
little piece of a guitar makes a difference in how it sounds, even 
if it is a small one.  I do believe that when I'm playing wood comb 
marine bands I hear a difference between them and a special 20, most 
likely coverplates and comb material, I would think. I like them 
all, but I guess I prefer wood because that's mostly what I've 
played for 43 years.   James
