I wondered how he got distortion on an acoustic guitar, I thought it was just because the level was too high but he's going through an amp to deliberately distort the sound. He has a very distinctive sound.
I'm pretty sure that according to the man himself, he broke the guitar accidentally, took it in to be fixed, got it back and when he tried it out, it sounded completely different. But he stuck with it because he liked how it sounded.
