He is highly sought after in Nashville as both a live and studio musician and is the owner of TuneSquad studios. Clark has a degree in Jazz from the University of North Carolina Greensboro.

Cassandra is originally from outside of Pittsburgh, Pennsylvania and is a violinist. Although she grew up playing country and rock and has worked with many great artists, she is most known for touring all over the world with international Bollywood star Arijit Singh. She has a degree from Penn State in Industrial & Manufacturing Engineering with a specialization in product design, minor in Entrepreneurship and Innovation, and is a graduate of the Schreyer Honors College. She is also the co-chair of the Women in Music Nashville chapter and strives to empower young musicians and entrepreneurs, especially women, through her professional and non-profit work in the industry.

Cassandra was recently named the 2024 NAMM Female Entrepreneur of the Year. Congrats!

Pat Geraghty is the inventor of the BrownBox and the original founder of AmpRx

We are proud and honored to have the opportunity to continue his legacy. We took this photo in the rain on January 1, 2022, right before we left Maryland to move AmpRx to Nashville.

Thanks for everything, Pat.
