CAJUN ACCORDION DISCUSSION GROUP
3 buttons added in the middle of the treble side. That covers the scale doesn't? 4 buttons on the bass box.
This is what Steve wrote on Facebook about the three buttons; 3 additional buttons are: from top G# push/Bb pull, middle button is Eb push/C# pull, bottom is Bb push/F# pull. I'm also curious about the Bass-side-configuration? Bryan post something about the accordion Link#2 Picture Link#3
