Silver Basic Kit

From $120.00

Elements. DIY.

Hairball Elements Silver is our DIY platform. It's our basic kit with metalwork, faceplate, PCB, and basic components. Here is your chance to design a mic pre.

The Hairball Audio Elements PCB is a highly configurable PCB that can accommodate several input and output transformer footprints. The concept actually began as the Eisen Audio DIY500, a popular kit that allowed users to build their own 500 series mic pre. After it was discontinued, many in the DIY community missed the extreme flexibility the PCB offered aspiring designers. Working with Eisen Audio, we've been able to bring it back, and it's better than ever.

Shortly we'll be posting some technical documentation to assist you in component selection. In addition, we'll host a user section where builders who wish can share their custom builds.
