Juan Alderete

Bassist with Marilyn Manson, The Mars Volta, Racer X

Juan Alderete is an Amptweaker TightDrive endorser, and was the bass player for the Grammy award winning band The Mars Volta.  He joined the band in 2003, and has also recorded with Volta’s composer/guitarist Omar Rodríguez-López on his solo albums.  Since joining the band, he’s played in Madison Square Gardens and was featured on the cover of Bass Player magazine in March of 2005.  The Mars Volta toured with Soundgarden on their big 2011 reunion tour.  In 2012 The Mars Volta disbanded and he started a new bandwith Mars Volta singer Cedric Bixler-Zavala called Zavalaz.

His early progressive rock and jazz interests combined with his studies at the Musicians Institute in Hollywood have helped him incorporate styles that make him a very unique sounding yet solid player, and this helps The Mars Volta create such interesting and experimental sounds.  It was at the Musicians Institute where Juan and fellow classmate Paul Gilbert created the band Racer X.

Aside from Zavalaz, Juan has been involved with his own musical projects. Big Sir is a group composed of Juan and singer Lisa Papineau. They have released two albums, and are currently recording a third. Vato Negro is a group with a revolving door of musicians, including Deantoni Parks, Omar Rodriguez-Lopez, and Jon Theodore.  Juan also played in an experimental futuristic rock trio called Halo Orbit, with drummer Mark Guiliana(David Bowie, John Scofield) and guitarist/synth player suGar Yoshinaga(Buffalo Daughter).

In November of 2017 Alderete filled in on bass for Marilyn Manson at the Ozzfest Meets Knotfest festival, and has been Manson’s bass player on tour since.

Juan also launched his own website devoted to pedals and effects, where he does many reviews and video comparisons…check it out:

After a solid day of blasting my ears looking for pedals at NAMM, the Amptweaker Bass TightDrive caught my attention as the tightest distortion.  It has the sound of grind with the low end intact.” – Juan Alderete
