Zacky has played guitar since he was around thirteen years old, and is self taught.

In the Avenged Sevenfold DVD "All Excess" he recalls that before Avenged Sevenfold, he played in a one time punk band called MPA*, which stood for "Mad Porno Action". He implies that they were not successful, and was arrested after their concert for supposedly "stealing all the mics." He and M. Shadows (the band's lead vocalist) formed Avenged Sevenfold. He took the name Zacky Vengeance, stating that he had grudges against many people who doubted his success. He was also responsible for the creation of the acronym "A7X". Stating that the 'A' stood for avenged, and then the 7X was seven times.[1] He is also left handed. He taught himself how to play the guitar when he was thirteen. The guitar he first learned on was actually his dad's, and was a right-handed model that he played upside-down.

Baker has stated that there are many bands that influence him. "I still love the heavy bands. I love... Danny Elfman and Elvis Costello. [It's] all over the place - I think that's the best way to be."[2]

Baker has been sponsored by Schecter Guitar Research since 2004, and has custom S-1 models out. He uses Seymour Duncan Pickups in all of his guitars and is currently a featured artist on the company's website along with Synyster Gates.

His brother, Matt Baker, is a member of the band The Dear & Departed. He also has a sister named Zina Baker.

Contrary to popular belief, Zacky's middle name is not Jonathan, he stated this himself on a Vengeance University MySpace blog. His middle name is James.
