[Harp-L] comb design/structure

["Marc Molino" <mmolino54@xxxxxxxxxxx>]

If you look into the hole of a diatonic harp, why do some models have a bar 
running horizontal across the middle of the comb (e.g. Golden Melodies) and 
some have none (e.g., Marine Bands)? Is this a manufacturing issues w/ 
plastics vs. wood? Are there plastic combs that do not have such a bar? Are 
there wood combs that do have this bar? It does not seem to have any impact 
upon the sound, but it would seem like it should affect airflow somehow...

Curious,
Marc Molino
