Schubach is involved in a heavy metal side project called Solace. He is the sole member of the band, recording guitar, bass and vocals in a D.I.Y.-fashioned home studio. The drums are added in digitally, through the use of a program on his Macbook. During the funding stages of this side project he provided incentives to individuals and bands in return for financial support using crowd funding platform Kickstarter. As part of this incentive scheme Karl Schubach provided guest vocals on a song by UK metal/hardcore band The Divided.
