Salut!
As no one had done so until now, I decided to record a little clip showcasing the great Tribo-Tone tone bar:
https://www.youtube.com/watch?v=_BOUNUxJ-L8
I play my Lazy River Weissenborn in G minor tuning (tuned a bit below G in fact). The song was written in the 1960s by the late Swedish genius Cornelis Vreeswijk. I came up with the arrangement tonight, so it's a bit sketchy at points. I have translated the lyric in the youtube "notes" for those interested.
I think/hope the character of the Tribo-Tone comes across in the clip, at least the way it sounds when I play it (including some swooshing with my hand along the strings).
Mon Dieu - it's late! I need to sleep!
