After a long time trying to deal with sore necks etc, I changed to the BG harness a few years ago. It works great, and my neck problems are no more.
But Ive always felt a little constrained with it. It is too close to my body and not very flexible.
So yesterday I was round at a friends and he has one of the Jazzlab saxholders. I tried it and it felt good. Sax felt very light and I was able to get it away from my body a bit. ( this is tenor). He has let me borrow it for a few days to try for extended period
I practiced for about an hour last night , and it felt good. No neck pain and I enjoyed it.
But the tops of both shoulders were a little sore.
He is a little bigger than I am but I didnt want to bend the part that comes in to contact with my shoulder, as it felt comfortable enough.
So, today, Im going to try again. And see if the soreness is there again.
it did make me think though about trying another type,
A bit of research did suggest the Vandoren harness, which looks a bit industrial, but gets good reviews.
expensive, but in the grand scheme of things and given the hours of comfortable use I would get, it seems ok.
ie how much would I be happy to pay for pain free sax playing? A lot more than the cost of this.
I would also be interested to hear from folks who have tried the Jazzlab and the Vandoren
