I'm waiting for my 1st concertina to arrive, but in the meantime I was looking at some layout charts for the 20 btn anglo and noticed a confusing discrepancy.
I THOUGHT the left hand G row goes:
Push-G, D, G, B, D
Draw-D, F#, A, C E
but then I saw a chart in which the first button on that row is different:
push-B, D, G, B, D
draw-A, F#, A, C, E
so is the first button G/D or B/A? Maybe that's a different system?
Thanks for any help!
