I really appreciate all the helpful information on your comments, I wasn’t aware of certain things.
The only reason I associate this box with the chinese ones are because of the plastic buttons which imo are not desirable at all since the playability isn’t great.
I’ve never had or played a bandoneon before, so I had no idea of the characteristics of this instrument; thanks for the information and sure I will edit the description.
I myself started with a Hohner english concertina, I can only remember opening it once or twice. As far as I can remember, it didn’t have a reed pan like this german one, instead, there were like 4 pieces folded in (with the reeds inserted). That’s what I meant by ‘foldable structure’. I also had a Gremlin (Stagi) 56 key with the same sort of structure. (Sorry if the description doesn’t make much sense but I cant remember very well!)
In terms of sound, certain notes (specially the high notes) sound a little louder than others, I don’t know why this could be. You can’t play very fast with this concertina because of the the plastic buttons and also because the springs are not great quality sprigs such as the vintage english ones. However, the chords sound very nice and I think it would be great for accompanying rather than for solos, but then again is not in modern pitch.
Thanks for the information about the pitch and the reeds, I will add it to the description!.
Unfortunately, although this concertina is more beautiful than the chinese ones, it’s still far from the quality of the vitange ones made in England. Lately, many Lachenal tutor models have been sold on ebay at around £150-300, which is a relatively cheap price and I haven’t yet received an offer for this one, so I’m afraid I can’t sell it for much higher, which suggests me that there is very little interest on concertinas that are not English-made.
Anyways, thanks again for all the useful information!
