Edeophone Differences in General Concertina Discussion Posted June 6, 2008 hi could any one please tell me the main differences between the majority of edeophones from the '20s...serial numbers in the 50,000s ,compared with earlier edeophones from say the late 1890s!! In terms of loudness, tone action and build quality. having read previous threads buying an edeophone seems to be a bit of a minefield.Is the variation in quality mainly within the later ones or is with all edeophones? finally given a choice which would you buy? ...("buy an aeola instead "is not an acceptable answer!) thanks very much..
