I started uke 14 months ago, just take a look at my first video, I was rubbish!
Joining in on the Seasons really helped me to develop & gain confidence, they are a great bunch of people.
The mic looks like it will work well enough, I started out using a cheap digital camera, & I've just bought & used a £17 USB mic for one of my entries.
You may have to play a bit louder than you think at first, but you can find that out in the comfort of your own home.
Nobody saw my face for at least 6 months, I didn't want to scare them!
Same with 'singing', just wasn't comfortable, but I can just about manage a bit now & again.
My advice, join in & have some fun.
(You don't have to commit to every week just when it suits you.)
