For non accordion players the Hohner Gola Freebass in the video would cost more than $40,000. I played a standard Gola at a music store while I was traveling overseas. It was $35,000, but it didn't sound as good as my Titano.
$35,000 - $40,000 for accordions, and we think arranger KBs are expensive ...
But when I think about it, in the early 1960's my SANO double tone chamber accordion cost $1,200 ... a LOT of money in those days ... but what a great sound ...
