Although he was a staple member of Strapping Young Lad at the time, he joined Fear Factory as a full-time member in 2004. He made his Fear Factory debut on their 2004 album Archetype (note: Byron does not play on the album as all bass tracks were recorded by guitarist Christian Olde Wolbers). Byron insisted his allegiance remained with both bands, as well as with Zimmers Hole, a somewhat comedic band he plays in with fellow Strapping Young Lad musician Jed Simon amongst others. Strapping Young Lad disbanded in 2007, allowing him to concentrate more on Fear Factory until his departure in 2012. Throughout his time in Fear Factory he did not record on any of their albums, possibly due to either contractual reasons or other commitments.
Byron is also involved with Jed Simon's Tenet project.
In early 2011 3 Inches Of Blood asked Byron to become their new manager. In January 2012 he joined them as their new bass player. In February 2012 Byron left Fear Factory as Bassist and was replaced by former Chimaira rhythm guitarist Matt DeVries.
