How are the buttons arranged on the box with eight bass-buttons?
Would you please send a photo of your special box.
It's usual to have eight bass-buttons on a two-row accordeon.
Here they use mostly two row accordeons with a C and a F row or A/D or G/C.
That's different then the Irish players use.

can't post a pic right now but will try later...

It is a C one row accordion

I have 2 buttons just like a regular one row (c on push and g on pull)

all the other pairs are the same push or pull--no difference--F pair, D pair, and G pair. If I redo it, I will change the C/G pair to a C both ways. It works great and makes for a very smooth accompaniment even though you have to push and pull for alot of changes on the treble side---the bass remains correct for the chord changes of the song.

How old is that accordion Chris? have any idea.
Thanks

it is about 19 years old (mine). Mr. Duhon's is older...probably at least 25 years old.
