This sounds brilliant. My partner and I are both interesting in taking up the anglo concertina (she plays melodeon, I play mandolin), but the starter Stagi models are all so ridiculously large, and we both have small hands (which is why I play a mando, not a bouzouki).
We did have a fiddle with a 20-key Lachenal in The Music Room in Clecky, which was a lot more comfortable, both in terms of key spacing and hand-strap style. Are the Wheatstones of a similar scale?
Going vintage is a bit intimidating for a first-time buyer, and the price of 30-key vintages is somewhat prohibitive.
Any idea when production will hopefully kick off? In time for August next year?
