sharps and or flats.. like on a Club system.. this is a classic ORGANETTO.. these babies squeal! very wet tuning.. best for playing tarantellas at your Godfather's exorcism.. very unCajun sounding.
That is interesting. Like Glenn says, the extra buttons add non scale notes, just like a Club model.
I have never seen a Baffetti like this before, but I did play a similar accordion a few years back. I think it was called Zero Sette, or something like that. That accordion was LOUD! It was much louder than the average single row accordion, which are themselves typically louder than other accordion types.
They provide you with accidentals. I believe they are the same on the push and pull. On a C box they would be F#, Bb and C#. Anyone know any different?
