YouTuber Digital Wishes found a child's keyboard lying on the street, so naturally he fashioned it into a distortion pedal for his iPad! Love that analog warmth!
I found this Hey Music Junior on the street this morning. Signal from the ipad is sent to it using a 3.5mm input. Heavy distortion complements of the keyboard.
