BIO: Mason Marangella began Vertex Engineering in 2006 as a small custom shop in Berkeley, California, taking on small electrical engineering and design projects from local recording studios whilst attending the University of California, Berkeley. Soon after, he started to work as a contractor and consultant doing ghost designs and collaborative projects in the pro audio, guitar pickup, effects pedal, and tube amplifier fields.

In 2009, after having worked directly with many local musicians and artists along with the experience of completing several electrical design projects for both large and boutique companies, he developed an understanding of what was missing and what needed to be improved upon with both effects pedals and rig integration with a specific emphasis on networking devices for the best possible sonic performance. This is when Mason expanded Vertex Engineering with a new division called Vertex Effects Systems, which would focus on designing and integrating electronic devices as a network of effects, customized for the needs of each player. Within one year Vertex Effects Systems had been commissioned to design custom devices and systems for some of the most prestigious musicians in the world.

By 2011, after a successful two years Vertex Effects Systems, Mason expanded another division of Vertex Engineering called Vertex Effects to design the highest quality effects pedals and modifications for both reliability and tone.

All Vertex products are hand assembled in the San Francisco Bay Area with premium handpicked components from only North American companies. Each product is built in small quantities and rigorously tested for the highest quality and consistency. In 2011 Vertex released the Vertex Axis Wah, Vertex BC109 Fuzz and the Michael Landau Signature Arion Chorus.
