I used to only be able to play standing up, now I have to lock the brakes and just scoot forward a llttle in the wheelchair the arms are real short so it doesn't get in the way.
I need a chair at home because most of the time, there is something on the computer screen that has my attention: music, lyrics, DAW. I do finally have a chair downstairs but I never use it unless I am doing an interview/podcast down there. All the amps make a better backdrop. I stand when it is my time to riff and let loose.
