Hahah, I do play some guitar. But it's just the basics though.
I think I know just enough to learn a song on my own. 😛
I usually record the piano chords first, just to map out the length and sections of the song.
Helps me figure what I can come up with or experiment with.
And then record the guitars and finally the leads. Not sure if that's the standard way of doing things but it's how I've been doing it 😄 Always experimenting.
