Interesting, and much nicer look than it just loose. I never use the soft flex tube but do use the the hard flex tube for the Hammond Melodions when playing in a sax position. I now tend to use the more conventional trumpet position just because I like playing in a downward position. I will have to give it a try and see if I like it. A few years back I connected a long clear tube to my Vibrandoneon and taped it to my mic stand? I sat the Vibrandoneon on shelf above my keyboard so I can play chords on my Kurzweil and lead on the Vibrandoneon that was fun.
