Kurt Ballou, music producer and guitarist for the metal band Converge, made his business card a distortion pedal. Read that again. It’s a printed circuit board that can be used to build a working distortion pedal Ballou calls the “Brutalist Jr.” With around $40-50 in parts, he created his own unforgettable moment with proof you’ve met him. The only way to get the card is to see Ballou on the street or at a show.
