Mod Kits

We offer two distinct mod kits, each representing a specific circuit design. Each kit is compatible with a number of different mics in various makes and models. Click on each kit to view more details and a complete list of compatible models:

The 990 Mod Kit – This kit works for many small, medium, and large-format mics (I say “format” rather than “diaphragm”, because some medium and large-format mics actually use a small diaphragm capsule). All of the mics that are compatible with this kit use a copy of a classic Schoeps transformer-less circuit.

The 2001 Mod Kit – This kit works for several popular large-format mics. All of these mics use a copy of the classic Neumann U87 circuit–one of the most popular recording mics in the world.

IMPORTANT: We ship only to the Domestic U.S.–no International orders, please.

Compatibility

Please note that our mod kits only work on versions of these mics that use through-hole components (as opposed to surface-mount or SMT). Please consult the Compatibility page for complete details.
