As a service to the pro-audio DIY and microphone modder communities, we have created the best low-price microphone capsules on the market. And we’ve recently expanded our product line with microphone modification kits.
Microphone Capsules: K47, K67, K87, CK-12
We started with the RK-47, a true 34mm K47 large-diaphragm condenser capsule. It is a beautiful upgrade option for hundreds of over-bright microphones. This is a capsule you’ll find uses for in every session.
From there we branched out. We now offer a second K47 type, the vintage-voiced RK7; a CK-12 type called the RK-12, and three versions of Neumann’s venerable K67: the RK-67, a faithful 6-micron copy of the original; the RK-87, a 3-micron version of Neumann’s K87 (with insulated backplates), and the new K67LE, an all-brass, limited-edition capsule.
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.

Mic Mod Kits
Our new “mod kits” let you turn inexpensive microphones into studio workhorses. We have a basic kit for beginners, so you can get into your first circuit upgrade for less than $50. And we have kits that require a bit more experience, but deliver a fully rebuilt and optimized circuit — something that will go head-to-head with the best condensers in your mic locker.
We have circuit upgrade kits for the Apex 460 and Alctron T-11 tube mics, and numerous FET mics: MXL 990, 990S, 770, V63M, 2006, V250 and (MCA) SP1. These are low-cost microphones with “good bones” — reasonably well-designed circuits that are somewhat crippled by the reality of meeting a low retail price point. By rewiring a critical portion of the circuit, and upgrading key components with audiophile-grade parts, we’re able to make these inexpensive mics compete with the high-dollar pedigreed mics you normally reach for first.

HOWTO / Tutorials
We have created several photo tutorials on large-diaphragm condenser microphone capsule replacement. The “microphone capsule swap 101” page shows step-by-step instructions for installing one of our large-diaphragm capsules. See also our listing of microphone capsule installation resources.
