To be honest, there is probably something wrong with your sitting position. The Dynarette (or any guitar support) wont' help until you find out what you are doing wrong in your back and figure out a way of correcting it. Guitar supports are merely tools to aid you AFTER you resolve the problem.
For example, the reason why I went to a guitar support was because of 2 factors.
1) My footstool was so high, that when I played, my left foot was at such as steep angle that I started to hurt. Also, I was leaning over to my left, a lot.
2) I was experiencing lower back issues while practicing.
I went to a flat footstool to rectify in the issue with my foot, because after one intense practice session I was in a lot of pain. It was then my teacher suggested a guitar support. I continued to work on my posture using the support.
Now after using a support for about 5 years, I find that I can go back to a footstool and apply those same concepts when I use it (I use it in lessons a lot of times). However, I notice that I still get back issues. And I've attributed it to the fact that when my left foot is up, I'm actually creating tension in the lower left part of my back (where I feel the discomfort).
Long story short, the support itself is NOT the solution, rather a tool in your solution. You need to find out where and how to deal with the pain you have.
