D.W. Fearn is a U.S. company founded by Douglas W. Fearn, whose lifelong passion for music, recording, and vacuum-tube electronics shaped the brand’s signature sound. Rooted in decades of studio and broadcast experience near Philadelphia, D.W. Fearn is known for handcrafted professional audio equipment built with meticulous testing, classic tube design, and a deep commitment to natural, musical sound. In 2017, after years of apprenticeship on the workbench and in the studio, brothers Geoff and George Hazelrigg of Hazelrigg Industries assumed D.W. Fearn’s manufacturing, marketing, and business activities. Doug Fearn continues to act as the principal product designer and serves as a consultant to the Hazelriggs, while Hazelrigg Industries manufactures and services all D.W. Fearn and Hazelrigg equipment in Bucks County, Pennsylvania.
