I am asked where it is possible to find strips to replace those of an old bandoneon. It so happens that I recently needed to change my bandoneon’s thongs and did not take the time to see if it was possible to find them on the canvas. This is probably possible, but certainly more expensive than it really is and it will certainly require a delivery time.
So I went to my favorite shoemaker, mine is on the market place in Bégard (22) and I brought him the bandoneon, he extracted a thong, the white, left in the photo. He then took a piece of leather 3 millimeters thick in which he cut 2 strips.
It took a few minutes and cost me less than 10 euros …
If you want to change your straps, you can use the picture below, the dimensions should be the same for all standard bandoneons.
