I play bass and I have one arm.
Most of my videos will be me playing my bass. While I do (of course) enjoy the praise (or constructive criticism!), what I'm really trying to do is to give other "disabled" people some encouragement to achieve things that they and others would doubt possible - I started playing bass because someone bet me I couldn't. This isn't just to get other one-handed people to play guitar (though if you want to, that's great!) but just to get into the mindset that if you want to do something, go for it!
I'm now on twitter, though I'm not sure why: www.twitter.com/OAB86
Please note that I don't use tabs. Sorry!
