About This Listing



The V4 was designed in the USA, and undergoes final assembly in sunny Southern California. We perform 100% quality control – every single piece of your microphone kit undergoes a series of stringent audio and visual tests here in Southern California before being hand-packed.

Every part of the V4 was designed to be robust and reliable. Wherever possible, components were over-spec’d. The deep-cycle cryogenic treatment improves the lifespan and performance of critical electronic components. Brass, steel, aluminum, and zinc are part of the heavy-duty construction. Every Vanguard microphone is backed by our FIVE-YEAR WARRANTY.

We run every one of our microphones through a series of tests to ensure that they meet our standards, and we strongly feel that any pair of V4s will match each other close enough for any critical recording applications.


We designed V4 with certain characteristics of classic FET microphones in mind, while also utilizing modern technology & design to meet the demands of today’s recording professionals. Our ultra-thin 3µm edge-terminated capsule diaphragms are extraordinarily sensitive, ensuring that every nuance and detail of the performance is faithfully captured.

We heard from a number of Vanguard V44S users that they loved the clean and full character of the V44S so much as an alternative to their V13 and V1 microphones, they wanted a small “mono” version of the V44S for travel purposes. The signal and power paths of the V4 is identical to a single channel of the V44S, but because we had space for an extra PCB and switch, we couldn’t resist adding a simple pad/rolloff combo switch to the rear, as well as spacing the power conversion circuit as far as possible from the signal path.

After hundreds of hours of listening with world-class engineers in environments ranging from fully-equipped major studios to bootstrapped home setups, we can confidently say that this microphone will vastly exceed the performance of other microphones in its price range, and rival the performance of microphones costing several times more.


The VANGUARD V4 is very different from other microphones in its price range. It is designed and precision-built in limited quantities to “no-compromise” standards, with final assembly and 100% testing taking place here in Southern California. We feel that the sensitive nature of microphones requires a high-standards, no-holds-barred test battery to ensure that we’d be proud to use EVERY microphone that leaves our shop on our own records.

We started with an extra-large 34mm edge-terminated, gold-sputtered 3µm Mylar dual-capsule assembly and custom-voice it with a proprietary hand-tuning process. The capsule is mounted in an open-weave headbasket for a natural sound with low internal reflections.

We then designed a transformerless solid-state circuit that matches the unique musical properties of our capsules and loaded it with premium-grade, over-spec components sourced from manufacturers around the world, including Germany, Japan, and the USA. We deep-cycle  cryogenically treat critical components in the signal & power paths, including an ultra-high-grade FET that is many times more expensive than the standard transistor you’ll find in most sub-$500 microphones. As one of the most critical components in the signal path, we tested several premium-grade transistors before choosing this particular model, and the results are significant & audible improvements in audio quality, headroom, distortion, and noise floor vs. standard-grade JFET transistors.

Aesthetically, the precision-machined brass body is coated with our signature Pinot Noir, finished with a deep, lustrous gloss, and accented by polished nickel trim and a precision-cast Vanguard badge. Your V4’s serial number is laser-engraved on the lower rear of the microphone.

The V4 was designed by a team of experts with more than 65 years of experience and vetted by award-winning engineers and producers.
