I suffer a lot of lower back pain. This is unavoidable due to my physical disability. It restricts my playing to seated most of the time. I like playing while standing up. A few songs later, I can no longer bear the pain so I have to sit down for a few minutes until the pain has abated.
I use a back support for gardening work and am considering using one while I am playing music too. I experimented with strap lengths for my bass and have arrived at what I think is the optimum length for me. Not too low or too high.
So does anyone here use a back support when playing guitar or bass?
