Very relaxing.....acutino?

[Tom]

Love this accordion and cello duet, very relaxing. Double cassotto with "acutino"? Special design element to enhance the cassotto sound?

Tom,
Lots of treble keys!?
That cello case kept making me feel there was a trio?.
Thanks for sharing!??

The notes at the end of the clip say it is LLMH (16+8 in cassotto, 16+4 out) -- a combination I've not run across, and don't see advertised on Ranco's website. My ear is not good enough to tell whether that's really what I am hearing or not.

I can imagine a LL right hand register giving the impression of 'enhanced cassotto sound'.
