The Vanguard V4 is a large-diaphragm multi-pattern FET condenser microphone. Lovingly crafted by experts over 2 years, it is designed to be a versatile, reliable, professional recording tool that breaks the usual “bang-for-your-buck” curve. With our  acclaimed edge-terminated ultra-thin custom-voiced capsule, a pad/rolloff option, primo cryogenically-treated componentry, and the best shockmount in al the land, the V4 is made to be your go-to workhorse microphone at a price that won’t break your piggy bank.


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.

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.

When you buy a V4, you also get a VLSM Heavy-Duty Shockmount. We wanted to rethink the standard “spider-style” shockmount of old, and designed the VLSM with a few nifty features. First is the open front, which allows you to position the microphone as close to the source as necessary. Second, we install aerospace-grade suspension rings that won’t break, sag, crack, or stretch over time. This shockmount was designed to fit any microphone with M22x1 threading, so you also can use it with a number of microphones from other manufacturers.

When not in use, your V4 should be stored in its padded pinewood box.

“I’m shocked at how well this microphone performs, and when I consider its price tag I am absolutely blown away.”

Tony Vincent, Tape Op Magazine

“Vanguard is on a roll….impeccable fit and finish, great sound, and highly affordable.”

Paul Vnuk, Jr., Recording Magazine

“…a focused, tight low end that keeps things sounding solid and crisp rather than glassy or hard…one thing that struck me immediately here is just how good the V4 sounds at different working distances…it could easily become a bit of a ‘go-to’ in the mic locker.”

Jon Thornton, Resolution Magazine

“Within a few short minutes of powering the V4 up, I know this is a very special mic. Very proud to add it to the family!”

Ryan Delvie, Audio Engineer

“Once I plugged in my V4, my vocal came alive…Incredible smooth sound, clear and warm tone.”

Kurt Hoffler, Kmusic Studios

“[The V4] has a smooth, balanced sound that does not lose tiny details in the mix….full, but sparkling and smooth. I have to say that with a beautiful design and a very pleasant and balanced sound, including a perfect shockmount and a favorable price, the V4 microphone is a very intriguing option…being a microphone of this quality and accessories is a real win. I am convinced that [the Vanguard V4] will serve you in any demanding shooting and will be honored alongside more expensive models.”

Petr Los Diplum,

“This thing is built like a tank and beautifully made.”

Robin Lai, FYR Productions

“This mic takes so little EQ and doesn’t honk at you in the upper mids the way a lot of mics do…I’ve never liked my acoustic guitar more…”

“Everything I recorded with it has came out to where I don’t need to EQ it…you want your microphone to just naturally sound good, and you get that with the V4….I’m very impressed. It has a sound that I would describe as clean, open, forward, and full. It gives me everything I expect out of a transformerless microphone with it’s clarity and low noise…I don’t see many microphones with this feature set at this price range. The V4 is in a class of it’s own with this price and feature set.”

Christopher Czar Smith, Audio Czar

“I would like to know where Vanguard was when I was starting out in this business? Like other people I’ve tried many different mics (not mentioning the manufacturers out of respect). If I could have just found this mic first, I would have just recorded happily for a very long time. It doesn’t have any of the funky, sloppy treble resonances that a lot of microphones at this price point have.

“The microphone is very well built. The shockmount is awesome…a huge sound in a small compact format.”

Chris Johnson, Audio Engineer

“Just picked up my V4 and I’m really digging it after only a few short hours…I’m really excited to have found you guys. I have at my disposal some of the most legendary mics around, and it’s really nice to find a company that’s making really cool stuff.”

Dave Westner, Audio Engineer

“The V4 shines with a very transparent image, a tastefully controlled warmth and smooth, open highs. An altogether very round, pleasing sound image, which already includes a portion of ‘signal beautification’ and thus a great presence, with clear and well-distributed, pleasantly fresh mids…an independent, recognizable sound that takes a healthy middle ground between character and neutrality.” [translated from German]
