Born in Fort Worth, Texas, Johnny started playing guitar in his early teens.

After Moeller finished high school in Denton he moved to Austin Texas working in many of the city's well known venues and often soaked in the music of the constant stream of blues, and rock artists performing at Antone's .

Years later the Austin Chronicle quoted Clifford Antone (who also helped launch Stevie Ray Vaughan) as saying: "Johnny, nobody can burn like that kid.

"[2] By the time Moeller had joined The Fabulous Thunderbirds in mid-2007 he had toured North America, Europe, Australia, and Japan extensively.

Johnny Moeller is rumored to be the inspiration for one of the characters in Mike Judge's Beavis and Butt-Head cartoon.
