I have a Mc Can duet concertina, very good instrument (I am a beginner).
My problem is the following :
I feel (and have always felt this way from the very beginning) very uneasy with its straps, find it very boring to settle them, unscrewing and rescrewing ... the holes in the straps are either too near from each other or too far etc : tedious and boring job each time for a dubious result
So I'm dreaming, maybe I could get some adjustable straps for my duet, as are found herebove ?
on cheap recent ones :

or even as it seems on old ones :
