Which model sounds best on (vocals, drums, guitar, piano, cello, etc.)?2021-02-09T18:00:49-08:00

Well, “best” is always an opinion, but I will try to explain: Every transformer I offer is a world-class, audiophile component – not the $6 Chinese knockoffs found in low-end imports. They all sound great, and each one has its own characteristics:

  • Model 1 OTA-2: My dual-bobbin, high-nickel OTA-2 transformer is designed and made in the USA especially for Austin Ribbon Microphones. The BEST for midrange electric guitar cabinets. Great for vocals and horns. Strong high-end, really great response throughout the entire range. The only reason it’s less expensive is because I have them made in large quantities. Far and away the top seller.
  • Model 2 Cinemag: The best high end of the bunch, and nearly equal low-end to the Lundahl. Sibilant, yet not brittle like a condenser. awesome for full-range instruments like piano and drums. It’s the only transformer that is shielded in a Mu-Metal can to help reduce magnetic hum from nearby equipment. It has the longest wires, and therefore, it’s the easiest to install. The Cinemag is my personal favorite of the 3 transformers I offer.
  • Model 3 Lundahl: Lundahl transformers are imported from Sweden and have very short, fragile wires, making them the most challenging to install. However, they have the best low-end response, due to the physical properties of the core. Theoretically, it delivers sub-sonic response that is +2dB better than the Cinemag below about 30Hz. Great for double-bass and baritone vocals, whith a smooth and responsive top-end. (Thurl Ravenscroft would have loved this model.)
Did You Invent “The Hot Holder” Silicone Soldering Tool?2021-09-22T13:39:33-07:00

Yes. In the mid-2010’s, I thought of the concept, made a few models for myself, and used them in my garage shop to make and repair audio cables and solder wires. My grade-school daughter started using them to hold weird-shaped rocks while making jewelry for her friends, and everyone who saw it told me to sell them. I debuted them a couple years later at my booth at the NAMM Show in 2018, and that’s how it started. Now, RadioShack.com is the exclusive distributor of the “Original Hot Holder” for Audio, and I have a “PRO” model and one for DIY Guitar Pedals. They are all still made here in San Diego by local job shops, with supplies from local vendors.

Do I need a special microphone preamp? Can you recommend one?2020-12-16T10:02:53-08:00

A normal microphone preamp should suffice for most applications. For recording quiet things, you’ll need more gain, so a dedicated low-noise, high-impedance Ribbon Mic Preamp is be best.
Check out my Austin Mic Pre (AMP) Kit. An ultra-low-noise, high gain microphone preamplifier kit designed exclusively for Ribbon Microphones.

Will you build a complete Microphone for me?2020-12-16T10:12:32-08:00

YES!! I will hand-assemble and ship you a completed microphone in a wooden cigar box case for an extra $200USD.
(Note: Add $300 for an assembled True Blumlein™ stereo ribbon microphone.)
Please Contact Me for more information.

Will you sell me a kit of all the parts, so I can put one together?2020-12-16T10:12:14-08:00

Yes. I have DIY Ribbon Mic Kits HERE. They start at $235 with FREE shipping to any USA address. (CA residents add 8% Sales Tax)

Will you repair my “Brand N” Ribbon Microphone?2022-06-01T07:40:26-07:00

Yes! – I repair vintage and modern ribbon microphones. Starting at $100, but final pricing depends on an assessment of the issues, the model of the microphone, and what needs to be done (or un-done!). Please use the contact form to get a hold of me. Also, if you download my tutorial and are not afraid of a challenge, you can probably figure out how to repair it yourself!

Do you have a microphone I could try out?2020-12-16T10:14:47-08:00

Probably not, but feel free to ask anyway. Usually they’re already out, being lent to my friends or being used in my studio. I only have a few.

What do you recommend for a good ribbon microphone preamp?2020-12-16T10:18:01-08:00

Naturally, I recommend my Austin Mic Pre (AMP) Kit. An ultra-low-noise, high gain microphone preamplifier kit designed exclusively for Ribbon Microphones. However, any low-noise, high-gain, high-impedance preamplifier designed for ribbon mics – like the Grace M101, AEA TRP, or True P-Solo Ribbon – will help your Austin mic sound its best.

How much Phantom Power do your mic’s require?2020-12-16T10:19:25-08:00

NONE! AUSTIN Ribbon Mics are completely passive. Phantom Power may fry the element of these and most ribbon microphones. To be safe, do not use Phantom Power!

Do I have to use a Pop-Stopper (pop filter)2020-12-16T10:28:05-08:00

Sometimes. Any time you can feel a breeze from whatever you’re recording (voice, bass, clapping, kick drum) then YES. If it’s loud like a guitar amp, that’s fine, but a blast of wind from a “Popped P” vocal can damage the delicate ribbon.

Do you offer other colors than Purple for mono mics and Blue for the True Blumleins?2022-10-17T08:36:08-07:00

YES. Custom powder coat colors and textures are available starting at $45, and you can get as many custom-colored mics as you like for that $45. (2-stage colors are $90) I use professional powder from NIC Industries. It takes about 3 weeks for a custom color, and my local machine shop will powder coat your mic with any NIC color you pick. Occasionally I will have raw Brass bodies (un-coated) available at no extra charge. Please contact me for more information.
