the sound I hear in european accordion music is not going to cut through the sounds of the other instruments in a band unless it is amped up. It has a soft silky sound more or less. The cajun accordions from Louisiana & nearby places seem to have a much more raw & coarse sound which cuts through the sounds of the other instruments & makes itself standout a lot clearer. So I figure the reeds would not require as many hours of work in their production as the reeds of the other accordions that have a far more silky soft sound.
I figure there ought to be a factory in Louisiana that makes reeds & another that makes bellows. It sure would speed up production of cajun accordions in that area because people would not have to wait weeks or months for reeds or bellows to be delivered from overseas.
