I hve regularly played with a gd player too foe 24 years,What you are saying is not correct , because Am, has limited chord.
   neither is your statement about BC boxes ,for example some irish players play in c on them and use the correct basses like a c one row, using basses for key of c ,others play across the row and use basses others play across the rows and do not use basses
