Your Indispensable, Do-it-all Preamp/DI/EQ

If owning one device that can take any signal — mic, line, or instrument — and optimize it to realize its full sonic potential sounds good to you, Sweetwater would like to direct your attention to the Hazelrigg Industries VLC. The VLC is a mic/line/DI tube preamp/equalizer with a front-panel combo input that duplicates the rear-panel microphone XLR and incorporates a 1/4-inch phone jack for direct injection of electric bass or guitar, electronic keyboards, and acoustic instruments with pickups. The onboard 2-band equalizer is an LC (inductor/capacitor) circuit that offers passive EQ in the tradition of the classic passive equalizer. The VLC’s all-tube signal path and transformer-balanced I/O pump up iron-poor signals with glorious vintage-flavored euphonics to deliver splendid results on any source, while the onboard EQ lets you quickly contour it to perfection. Gear-savvy musicians and studio owners are raving about the Hazelrigg Industries VLC. Give it a serious audition, and you will be too.

The case for a high-end preamp

Your preamps are the lifeblood of your studio and — along with the denizens of your mic locker — the essence of its sound. A favorable-sounding live room is a plus, but we don’t all have the luxury of choice in that matter, especially if we’re recording while on the road. As the first component in your signal chain, the preamp is a make-or-break proposition. Skimp on quality here, and no amount of processing downstream can resuscitate the compromised signal. Conversely, record with the best preamps you can afford, and you’ll be delighted to find that — populated with vibrant, full-bodied instruments and vocals — your mixes will come together effortlessly, coalescing into radio-ready product that blasts right out of the speakers. World-class studios have long known the true value of great-sounding preamps, but studios of all sizes can leverage that same advantage with the Hazelrigg Industries VLC.

Amazing results from any source

With its crystalline transparency and prodigious headroom, the Hazelrigg Industries VLC delivers amazing results on any microphone. When even your inexpensive dynamics take on new sonic authority and dimension through the VLC, you’ll start to see the contents of your mic locker in a whole new light. The fact that it can handle and finesse all of your sources — be they dynamic, condenser, or ribbon mics; instruments; or line-level signals — makes the VLC invaluable for today’s hybrid studio workflows. Add in its intuitive, highly effective EQ, and you have a formidable channel strip — an indispensable do-it-all Swiss Army knife you don’t want to be without!

Incredibly useful for a broad range of applications

The VLC is incredibly useful for a wide variety of studio and remote applications and its elegantly simple and purposeful control layout gives you immediate access to everything you need. On the left side of its stout front-panel metalwork, you’ll find a combo XLR/phone jack input and a beefy gain knob. A chunky rotary switch selects between mic, instrument (DI), and the rear-panel balanced line-level input that resides alongside a redundant XLR microphone input. The all-tube DI signal path works its magic on electric bass, guitars, keyboards, synth modules, and acoustic instruments with pickups, while the line-level input lets you wire the VLC as an insert in your DAW or mixer to “re-preamp” tracks during tracking or mixdown. It’s a powerful secret weapon many engineers use to revitalize and pump new life into lackluster tracks. Punch up a stereo mix through a pair of VLCs, and you’ll never look back.

Quick, intuitive tune-by-ear EQ section

At first glance, the VLC EQ section’s Low and High bands, each featuring a Boost and Cut knob, bear more than a passing resemblance to the classic passive equalizer. But while very similar in concept, the VLC’s 2-band EQ section offers more flexibility in the low band than the old-school units in that it gives you a 2-way frequency selector switch for each knob that selects between lower and higher bands for its corresponding knob. The Low Cut control introduces a gentle roll-off shelf that’s ideal for contouring your bass frequencies while removing rumble and low-end mud. Similarly, the High Cut offers a gentle contour that’s adept at taming strident program material and minimizing converter aliasing issues. Together with the broad, flattering curves of the Low Boost and High Boost controls, the VLC’s LC equalizer provides highly musical sound shaping that lets you quickly and intuitively tune program material by ear. A handy toggle switch makes for easy EQ in/out comparisons. Veteran recording engineers know that the forgiving, broad-brushstroke curves of venerable EQ circuits such as the vaunted passive equalizer units are a valuable complement to the surgical sculptability on tap in many modern EQs. Both deserve a place in any well-equipped studio rack.

Hazelrigg Industries: sonic authority, handcrafted in the USA

Back in the Golden Age of Analog, pro audio equipment was meticulously assembled by hand using military-grade components — factors to which the timelessly superior sound and performance of coveted vintage gear are often attributed. Handcrafted in Bucks County, Penn., with premium parts, an all-tube signal path, transformer-coupled I/O, and a custom-wound inductor in the EQ circuit, the Hazelrigg Industries VLC is built this way. Its amplifier and power supply are designed by renowned electronics guru D.W. Fearn, whose VT-1 set the bar for modern tube preamp performance upon its launch in 1993. With its crystalline transparency and prodigious headroom, the VLC delivers sumptuous results on any microphone. Factor in its ability to impart its sonic charms to line-level signals and DI sources — and let you tune it all by ear — and the Hazelrigg Industries VLC becomes a must-have piece of kit that deserves a place of honor in your studio or remote rack.

Reviews

Truly inspiring piece of equipment
A recording & mix engineer's dream. It has an elegant Preamp with a front faced mic input & DI for quick/easy recording. The EQ is lush, musical, and never harsh on the ear. Quality control is top notch and these are built to last a lifetime. Recording through a VLC is great but you can also mix through it like a channel strip on a console. Except the VLC sounds better, gets results faster, and is much more reliable than any console. A pair of these have completely transformed my workflow. I'm looking forward to getting a handful more of these. A truly inspiring piece of equipment.

Boutique tube excellence!
I am fortunate enough to live in the same town as George and Geoff Hazelrigg and I've owned a pair of these units for the last two years and they are fantastic!

A true audio Swiss Army knife. The Hi Z input on the front is so much better then any other DI solution (except theirs lol), anything I need to plug in directly goes through these units. Having the XLR mic input on the front is also extremely handy (there are also both Mic and line XLR inputs on the back).

The EQ is "pultec style" but it's different from your typical EQP. extremely musical and high-quality like the preamp, you just have to play with it, there's no way to accurately describe it. The preamp and the EQ work seamlessly together differently from other channel strips. The EQ really feels like it's just "tuning" the mic pre, which is great!

for what it's worth, I've been to the shop, I've seen these guys making these units. This is the real deal. there's a reason why you're starting to see these popping up in studios everywhere.

you can see in my pictures that I keep my units close to the floor so that I can plug the stereo output of my pedalboard into them with short cables

this is a purchase you'll never regret and will only go up in value.

Hazelrigg VLC - The New Gold Standard
I have been so fortunate to have had access to the finest most revered studio equipment around the world working as a professional producer for 26 years. Every so often there's that one piece of gear that changes everything, this preamp is one of them. Its difficult to put in to words what this box is capable of, it just does so much so well and while doing so imparts sublime musical clarity and imaging on a level I have not experienced before. I don't know what kind of Voodoo they came up with in this circuit, but its magical. I have other DW Fearn gear, a VT7 and VT5 which are equally as special. I am also very familiar with Dougs VT1 and VT2 preamps which this circuit is based on, but I have to say the VLC paired with this Pultec style EQ is in a league of its own sonically.

The Hazelrigg VLC is quickly becoming the "Go To Preamp" for top mixing engineers and producers. Notable up and coming producers like Jon Castelli, Bainz and Mike Miller who specializes in Atmos all rave about this box, and rightly so. In short, the Hazelrigg VLC is a modern classic, period said and done.
this ones a keeper.
Man, this is a really great preamp! I'm an Artist who engineers / mixes my stuff and this thing is now THE pre for my vocal chain.

I had used a BAE 1084 for a few years because I thought the 1073 was just what everybody else used so it must be a fit for me too, but nope! After trying it against a Neve Shelford, I realized the Shelford was a lot clearer and the frequencies I previously fought in mixing were just characteristics of the 1084. So I thought the Shelford was the ticket, but wanted to throw a tube preamp in the mix since I didn't have one & never tried one.

This is the one! what the Shelford lacked for me was a little bit of weight or thickness in the low end that the BAE had. By NO means is the Shelford bad, it's amazing and I use it on instruments all the time, but this is the perfect middle ground for me.

It's perfectly warm in the lows, perfectly clear mids, silky highs not harsh at all, the eq is very broad and sounds amazing, the high and low cuts are great, and the connections on the front make it perfect for me. Can easily quick swap mics, but currently have it paired with a 251 and it's a match made in heaven. No doubt it'll sound amazing on any mic!

Got me closer to the finished sound I want going in, which as a songwriter is invaluable to me - having inspiring sound that you don't immediately feel like you have to fix, you can hear the song come alive and it actually sound like a song hahah.

Can't recommend it enough, I guarantee you'll start to see more and more of these popping up in big sessions the more people catch on. Never getting rid of it!

Best tube preamp/ EQ money can buy!
Got a pair of these amazing units a few weeks ago and now I haven't had the interest to touch any of my other preamps. Seriously, this thing sounds HUGE and gives all my tracks the saturation I never knew I needed. Works well with all my microphones from LDCs, SDCs, to Dynamic microphones. Better yet, put a ribbon microphone and your job as an engineer is done. Sit back, have an alcoholic beverage and let your clients tell you how much depth and sparkle their song is sounding. EQ section is great, tracked bass recently and had the low boost cranked all the way up, still retained the punch and it never got "muddy". Top boost for that sweet sheen on vocals, strings, guitars and more but never have them sounding brittle. Big shoutouts to George, Geoff, Eric and the Hazelrigg team for making this happen. Seriously, sell all your existing preamps and get yourself a pair of these, or maybe 12
