I have Multiple Sclerosis and must play sitting down. I much prefer a folding chair to a stool due to stability. My experience as a bassist has been mostly electric bass, the only experience that I have with upright was an Azola Ampeg Baby bass that I owned for a few years. My question is to those who have played the Ibanez upswing or the less expensive NS. Can ether/both be lowered to a low enough height to be played while sitting in a chair of this height?
