Very impressed with the song. You called that a mini-guitar, is that what it really is? At first I thought it was a ukelele, but definitely sounds like a standard guitar range.
Oh and by the way the microphone you used did a great job of picking up the guitar and vocals in my opinion.
I also play guitar, but I have never been able to sing and play at the same time.
What are the requirements of doing a Hive Open Mic? I produce a lot of music now via software, and I was thinking of maybe trying that.
