AUSTIN Ribbon Microphone Kits are the standard for Do-It-Yourself Microphone Kits.
With an Austin Ribbon Microphone Kit, you get all the parts to build a world-class USA ribbon microphone in one package. Follow simple, step-by-step, fully-illustrated instructions & video tutorials to assemble the wire-mesh grille and ribbon motor into the powder-coated Brass chassis, and solder the connector & transformer to build yourself a professional Ribbon Microphone.
Specialty tools and templates are included in each kit, but you’ll need some basic tools like a screwdriver, razor blade and a soldering iron.

An Austin Microphone is a practical gift for a guitarist, drummer or singer, and also for an engineer or a student who needs a college lab project. My kits are already used in college courses at the Berklee College of Music in Boston, Conservatory of Recording Arts and Sciences, Art Institute (Ai) campuses, Community College labs, and audio engineering trade schools!

The kit is not for everyone: Building a sensitive microphone requires your patience to make mistakes while learning, (extra materials included!) Previous DIY experience always helps, and it can be assembled on a kitchen table in 6-8 hours. It is designed for adult DIY’ers and College labs… but even high-school students have built my kits as class projects and science fair entries.

Choose from 3 different models:

MODEL 1 – My AUSTIN™ OTA-2 USA transformers are custom-wound especially for me in Southern California, and they sound KILLER! Fat bottom punch, and excellent high-frequency output make the Austin™ Model 1 great for recording electric and acoustic guitars, and bringing-out the warmth of studio vocals.
MODEL 2 – The USA Cinemag 9887 Ribbon Mic transformer delivers slightly brighter highs than my custom AUSTIN transformer included with the Model 1 Kit, and is shielded in a Mu-Metal can for extra hum protection. It also has the longest wires of all the transformers, making it very easy to install. It has become a favorite for recording vocals and other full-range instruments like Piano and strings, without the brittle crispness of a condenser microphone.
MODEL 3 – The prestigious Lundahl 2912 Ribbon Microphone transformer is a favorite for Chinese Microphone Mods & upgrades, and delivers a wide, flat frequency response. Smooth, natural bass, and flattering highs – without the brittle edge of a condenser. The Lundahl 2912 helps your DIY Austin mic to rival the performance of boutique studio ribbon microphones costing WAAAAAY more!

Made in the USA.
Austin Ribbon Microphone Kits are not imported repackaged Chinese junk. My custom parts are hand-made in San Diego, CA by local vendors and machine shops.
I use UL/CSA wiring, custom-wound transformers, a Switchcraft connector, a beefy powder-coated Brass chassis, and a proprietary monolithic ribbon motor truss of my own design. Direct, personal customer support is always just an email away, and is usually answered within a couple hours.
