The Mach One Violin Shoulder Rest has been around for a long time. I've used the Mach One for the last 10 years and want to share my thoughts on what I think after 10 years.
Eric Mrugala is from Chicago, IL and started playing the violin at the age of three. He is an active performer and teacher based Massachusetts. Eric is dedicated to erasing lines between audiences and music through performance, and education.
