Re: Neck Problems
I just got a BG harness recently and absolutely love it. I switch between soprano, alto, and tenor, (not too much bari) and the sliders work very smoothly when adjusting between horns. I leave it all clipped together and put it on like I would a shirt, but it comes apart in places if you can't extend both arms at once to put it on initially.
I used to use a different harness (can't remember the brand) and I thought it was the coolest thing until I got the BG. The BG just operates more smoothly.
I'm pretty sure they come in different sizes. And despite the horror stories I've heard abot wwbw.com, I got mine from there along with a bunch of other gear (accessories - not horns) without any problem whatsoever.
I've got a stand for my bari that lets me play sitting from a stand instead of from my neck, but it wouldn't work for smaller horns as the metal brace is quite large.
I remember seeing a sitting-stand for alto/tenor, but I'm unable to locate where on the web I came across it. Sorry. You might be able to Google your way around to find it. With the BG putting the weight at your shoulders instead of your neck, you might find that's all you need.
And forget the Neoprene neck straps - no matter how wide they are, they still put the weight on your neck. Go for the BG Harness. They're awesome.
