It is like a Corona 3 layout.. I shifted the C row from outside to middle row.. the F row to inside row ( where on full Clubs there are enough buttons )..and added a G row outside..

It's kinda like it,s not pristine anymore.
May not be too good for Zydedco with the tone chamber. That gives it a distinct sound different from the useal 3 row.

..... pristine ??.. well it's neither immaculate, cherry, unique, .. but metaphorically they get the idea across better than.. purdy, tight, hottie.. heheh.

The tone chamber applies to only 2 sets of the 5 treble reeds ... which have a full blown zydeco sound..as does the 4 reed musette set-up .. Motor Dude never sounded this good..

If you play the muted tone chambered combinations..then you get a super duper Jazz box.. which, true, is wasted on a zydeco player .

Still.. I suggest any triple row players try an earlier Hohner Morino Club ( open it up too )..as well as the later Hohner Ouverture .. which has great zydeco potential..
