Moyer was born and raised in El Paso, Texas and graduated from Coronado High School. Moyer was formerly part of the Texashard rock act The Union Underground. Prior to his stint in The Union Underground, he was the bassist of the popular band Soak, also hailing from Texas. He is the owner and teaches at Natural Ear Music in Austin, Texas, where he works with a lot of young bands. Moyer works in partnership with Silver Tongue Management.
While he is still capable of playing finger-style, Moyer prefers picking over the latter because it has a more aggressive feeling.
On February 8, 2012, it was announced that Moyer joined the supergroup Adrenaline Mob while Disturbed is on hiatus.
On May 14, 2014, Moyer was involved in a tour bus accident while on tour with Adrenaline Mob supporting Avenged Sevenfold. No serious injuries were sustained by any of the band-members.
On August 4, 2014, Moyer announced that he would not be joining Adrenaline Mob for their upcoming fall tours. As a result, the band began looking for a new bassist, thus ending Moyer's tenure with the band.
Moyer had a custom line with Traben bass company. He and the company produced his signature Traben Havoc. He also has custom amps with Kustom featuring his own design printed on the front resembling a skull engulfed in flames.
Recently, Moyer has signed an endorsement deal with BC Rich Guitars, who now manufacture Moyer's signature Havoc bass. They can do this because they are owned by the same holding company as Traben.
