Warm Audio WA-67 Large-Diaphragm Tube Condenser Microphone

Warm recreated the vintage '67 mic for an affordable price -- from the EF86 pentode tube, to the custom Lundahl transformer, to the Swiss Gotham 7-pin cable.

In the Warm WA-67 large-diaphragm tube condenser, Warm went to great lengths to recreate the discrete circuit of the original '67 microphone, using boutique components throughout to ensure that nothing got in the way of pure tube magic. The sound and vibe of the original '67 is recreated in the WA-67, and Warm Audio takes great pride in being able to make such a high-quality microphone available to everyone at an unheard-of price.

Based around an EF86 pentode tube and having the same smooth and creamy tone of the original, the WA-67 excels at recording just about anything that you put it in front of, and it may immediately become your go-to choice for vocals, guitars, drum toms and overheads, pianos, brass and strings.

The Original '67

The original '67 became one of the most sought-after and widely-used studio microphones of its time, recording a massive collection of some of the most memorable songs of the last 50 years -- we're talking about classic tracks from artists as varied as The Beatles, Led Zeppelin, The Temptations and Nirvana! The original mics are still sought after, but they can command upwards of $8000 for a pristine unit, putting them far out of reach for most recordists. Thankfully, Warm Audio has now changed that scenario with the release of the WA-67!

The Capsule: The Heart of a Microphone

Even if you stuff a microphone full of premium components, if the capsule isn't right, nothing is - it's that critical. Warm went to great lengths to recreate read more the capsule from the original '67, making sure that it performs the same way, has the same frequency response and contributes to the same chewy character as the original. That meant not only ensuring that the hole pattern was identical, but also making sure to craft the entire assembly out of brass (including the mounting rings) just like the original design. It takes more time, and it's more expensive than using multiple types of material, but Warm felt it was critical to go the extra mile on this microphone. The results speak for themselves - the WA-67 sounds absolutely stellar!

The Guts and the Glory

The EF-86 tube is well-known in the industry for having characteristics that are consistently flattering to audio sources, and it's one of the reasons why the original '67 microphone remains sought-after (and why some modern audio manufacturers use it in their own hyper-expensive microphones and preamps).

In order to accentuate and complement the custom capsule and EF86 tube, Warm used top-shelf components to complete their version of the original circuit. They used high-bandwidth polystyrene capacitors, as well as boutique polypropylene caps from Wima and a large output capacitor from Solen. Just as important in a tube design, they also used a custom large-core transformer from Lundahl in Sweden, which plays a significant role in the buttery smooth high frequency response and huge three-dimensional sound of the WA-67. The microphone is also encased in a beautiful nickel-plated brass body and headbasket, which provides strength, additional shielding from extraneous handling noise and the ultimate in audio performance.

Last but not certainly not least, the quality of the 7-pin cable that connects a tube mic to its power supply is also of paramount importance - it carries both audio signals and voltage for the tube on different pins, which means that it plays an integral role in the performance of the microphone. That's why Warm partnered with high-end manufacturer Gotham Audio of Switzerland to use their high-end GAC-7 cable with the WA-67. This special cable is integral to the sound and performance of the microphone, and adds the finishing touch to the WA-67 system.

"My 4th and by far my favorite tube microphone"

Overall: 5 out of 5 stars
(see rating details)
This microphone blows me away every single time I use it. For starters, I haven't found a situation that it has not worked extremely well in. And out the 4 other "tube" microphones I own, It IS the BEST. I tracked 2 artists, using it on Lead vocals and I was amazed at the results. The top end is so so good on these mics. Trust me. No harsh artifacts from cheap parts. Beautiful low end and PERFECT midrange. Once again Warm audio has outdone themselves. The 3rd artist that I tracked with the WA67 was myself. I loved it so much that I ended up tracking my lead vocals with it on my entire new project! I would love to try the WA47 at some point but this thing is a absolute gem for the price. You'd need a billy club to try and beat it.
