This is actually most of what I use to create my music.
I have a couple of other guitars and one more synthesizer that are also part of my sound. I sometimes use found sounds, like the percussion in "Halloween, I'm Afraid". It's actually a glass jar I smashed with a hammer and then ran the recording through an audio editor in a computer. It came out sounding more like clinking chains than glass breaking but it works for the song. I made one short clip of it and set the space bar as a trigger and "played" it on the recording.
