Eric Valentine

Owner and chief visionary, Eric Valentine's constant experimentation and exacting standards  are what has molded Barefoot into the studio it is today.

From his very first Tascam 244 Portastudio to the Neve 88R, Eric has had his hands on just about every piece of equipment designed for the purpose of recording sound.  He brings the perspective and vision of an end user – that is still actively making records every day – to the design process. Striving to fulfill needs and solve the problems of today’s record makers, Eric created Barefoot and Undertone Audio as outlets for these ideas to be available to musicians, engineers, and producers.
