Iron Man - Black Sabbath Rock Harmonica

Watch my Black Sabbath harmonica videos: Harmonica lessons for this riff, see youtube video: Håkan Ehn plays Hohner Marine Band DeLuxe harmonica in G. Shure SM57 microphone connected into Boss recording studio. Boss BR-1200CD, digital recording studio: - bass and drums backing track - chorus effects - reverb - pitch shifter effects: harmonica, pitch -24 (two octaves lowered), D:E balance 60:100. D=direct. It´s the unprocessed harp sound. E=effect (pitch is shifted), in this video I lowered the pitch two octaves down. So it sounds like two harmonicas, one with natural sound and the other with pitch shifted. Here D:E = 60:100 which means I let the processed sound dominate.
