The Beta Machine
Matt McJunkins is a studio and touring bass player as well as a co-founder of The Beta Machine, who currently resides in Los Angeles, California. He has played bass in A Perfect Circle, Puscifer, Ashes Divide, Carina Round and 30 Seconds to Mars. He also sings backup vocals in all of these bands and plays some keyboard and guitar for Puscifer.
Early life 
McJunkins began playing bass when he was 13-years old. His older brother was a drummer and convinced him to pick up the bass guitar. He went on to play in his high school marching and concert band. After graduating high school, he went on to study at the world renowned Musician's Institute in Los Angeles. This led him to begin taking gigs all over LA for many genres of music.
Professional career 
Ashes Divide 
In 2008 he was selected by Billy Howerdel, co-founder of A Perfect Circle to play bass in his band Ashes Divide. He toured steadily with the band for the following year for festivals and headlining bills including Rock On The Range and Projekt Revolution.
After touring and performing with Ashes Divide, he was asked (along with fellow Ashes Divide bandmate, drummer Jeff Friedl) to join Maynard James Keenan's sideproject Puscifer for their first live performances. Since then he has been a part of the touring Puscifer lineup and also contributed as a writer and performer on subsequent recordings with the group. He contributed to Puscifer's album, Conditions Of My Parole.
30 Seconds to Mars 
A Perfect Circle 
In the fall of 2010 he was asked to join A Perfect Circle for their first live performances in 6 years, and has been a touring member of the band since. Replacing previous bassists, Paz Lenchantin and Jeordie White (Twiggy Ramirez), he has been received well by fans and critics and has received feature stories in Bass Player Magazine and Bass Guitar Magazine which praise his playing and composition.
The Beta Machine 
The Beta Machine is an American rock/electronic band consisting of Matt McJunkins, (vocals, bass, guitars, keys, programming) and Jeff Friedl (drums and programming). Little is known about the band at this time other than what has been posted on their website, Facebook and Twitter accounts. There have been photos of both members in the studio with Puscifer producer Mat Mitchell and Nightmare and the Cat vocalist, Claire Acey. 
Playing technique 
McJunkins began his career on bass as a predominant finger-style player, but upon joining Ashes Divide, Puscifer, 30 Seconds To Mars and A Perfect Circle, he now primarily plays with a pick. He often uses complex chord shapes in picking and strumming for all of the bands he plays with. He does, for the country music of Puscifer, still use finger style on occasion in their live show.
McJunkins plays Fender Precision Bass Deluxe Models that are 4-string and contain both the P-bass and J-bass pick ups. He tours with three of these basses, including the original black and white bass that Paz and Jeordie played previously with APC. He plays Mesa Boogie Big Block Titan heads through multiple Ampeg SVT 8x10's. He uses the Fractal Effects Processor for ASHES dIVIDE and APC. He uses Ernie Ball Power Slinky strings and Dunlop Tortex .88 picks.
