Big Crunch opened in February of 2008. The shop is located in Baltimore within Magpie Cage recording studio. We specialize in tube amp repair and design, and share a space with instrument specialists Old Town Lutherie. We are happy to help create your dream amp or pedal. All designs are created and built in-house by owner and tech, Brooks Harlan, and have been used by the Sword, Clutch, War On Women, Sparta, and more.
