Microphone Parts: Capsules, Mod Kits, and More

Large-diaphragm replacement microphone capsules

We believe microphones are essentially EQ devices. We further believe that if all your microphones sound the same, then your gear isn’t serving you as well as it could. We can help you build some extraordinarily musical variety into your mic locker.

We offer two versions of the K47 capsule design pioneered by Neumann. Both offer classic “mid-forward” presence, and a wonderful contrast to the over-bright condensers that have overtaken the market.

We have an AKG CK-12 style capsule to recreate the brightness and intimacy of the AKG C12 and Ela M 251 microphones.

And we offer a beautiful version of Neumann’s venerable K67/K87, voiced with a milder high-frequency boost than is typical for this design.

Circuit replacement kits

Our circuit replacement kits let you turn inexpensive microphones into professional-grade studio workhorses.

We have kits for the Fat Head (ribbon), Alctron T11-A / Apex 460 (tube) and numerous FET mics from Studio Projects, MXL, CAD, Apex, Nady, t.bone, and Golden Age -- low-cost microphones with “good bones.” By replacing the circuit and capsule with our custom parts, we’re able to make these cheap mics compete with the high-dollar pedigreed mics you’d normally reach for first.

Microphone Kits

We stock all-inclusive microphone kits, beginning with our justifiably popular RA-23 (now renamed S-47, S-12, and S-87). The kit includes a very slick, unbranded donor body, a premium circuit kit, and the capsule of your choice, enabling you to create a variety of sonic colors reminiscent of famous vintage microphones.

Hand-built Boutique Microphones

We stock a limited number of finished microphones, built in-house from our own kits.
