Hi to you all,
there seem to be built two different accordinas, one by Joseph Carrel who sells for example on ebay.de and ships worldwide (costs 1100€), one built by Claude Labourdette which seems to be the successor of André Borel (costs 2480€).
I didn’t play one myself but both of them really sound great; but what seems to be very interesting, Claude Labourdette claims having innovated the Accordina in a way that has been discussed several times on melodicaworld (better keyboard action, better airflow, improved air/water tightness…)
Unfortunately these are things that can only be proved by a player who plays such an instrument for a longer time (who would have thought that for example the old Vibrandoneon would have such flaws!).
