Vox MV50 AC 50-Watt Hybrid Tube Head Review

The leap from analog to digital is continually prevalent in the minds of music equipment manufacturers. This means that we're seeing some amazing hybrid amp heads appear. Circuits and enclosures are becoming smaller and smaller, as in all modern consumer electronics.

The capabilities of a lower wattage amp head are foolishly underestimated by some of us. New technological advances have moved it up a notch in the last couple of decades, and many of them now meet standards. Many have incredible levels of volume as well as lovely tones that sculpt your voice.


The MV50 amp head from Vox, with a micro-stature, is a mind-boggling palm-sized powerhouse. With smooth retro curves and a mirrored front-plate, it is well-built. It has all of the classic esthetics of Vox that you associate with the brand. Given its lightweight and micro-dimensions, the structure seems fairly solid.

It's pretty darn compact, weighing in at just over 1lbs, and made with a robust carrying handle. For someone who likes to ride with their ax and have an impromptu jam on the lane, this feature makes it a top pick. A lot of choices for microamps can be a little underwhelming. Most are judged rather than a viable piece of kit as something of a novel or novelty.

There are a lot of guitarists out there who are unable to consider anything but all-tube amplifiers - the MV50 is an authentic tube-tone reproduction hybrid style amplifier.

It has a mixed set of circuits. This utilizes two ground-breaking Nutubes instead of an old school tube transistor preamp. They were designed and engineered by Korg initially. These modern 'tubes' turn many a tube-head easily.

They are well built and offer the MV50 the ability to sound just with a hell of a lot more headroom like a maxed MV30. They are also an important component, setting it apart from other micro-amps.

They're the secret that gives it its excellent AC tube tones, enabling it to imitate the vintage era of British Music.

It has a no-nonsense set of three dials; volume and tone gain. The most interesting is the tone dial. You can dial in a wealth of sounds, despite its simple, solitary control process. Be it Queen-like tones influenced by the Beatles or glorious. You can use it in combination with the Gain knob that has a scuzzier, blurred tip, as you would imagine, the higher you lift it after the break-up.

This Tube Head also benefits from a power portion of the D Class, which means you can hook it up to most cabinets without any problems with consumption. The input-output is straightforward for such a small footprint.

For your guitar or other instrument, you have a regular 1⁄4-inch TRS input and a 1⁄4-inch out to run to your cabinet or amplifier. There is also a line-out or headphone link that is full size (1⁄4-inch). This implies that you can use the micro-head as a stand-alone for practice without a taxi.

Again, if you want to use it as a travel buddy, this is perfect, but it has a 19V DC power supply, so you'll need a hook-up.

Vox MV50

Summary

So much more than a gimmicky micro-amp head, the MV50 AC. It's built more firmly for starters than most microamp heads, but under the hood is where things vary the most. With some superior hybrid circuitry, it was decked out. We think this gives it the edge over other related items that are currently on sale.

It couldn't be easier to work with an easy one-in, one-out set-up and three basic front-mounted dials in hand. Apply to that the additional headphone performance bonus to practice without upsetting others, and you have an impressive piece of equipment.

It's compact and lightweight. You should throw it in a backpack and take everywhere you go the classic tones of the Brit-rock revolution. In place of its preamp, it features Korg's proprietary Nutube and has Class D circuitry that allows it to connect to any cab.

Pros

+ Amp head, micro-sized.
+ Power segment Class D.
+ Preamp Korg Nutube.
+ Analog/digital hybrid circuits.
+ Awesome-portable.
+ Built well.
+ tones from Britain.
+ Headphones to work solo.
+ DC power supply of 19V.

Cons

—Just running in DC. Given its small size and portability, the option of being able to control it with batteries may have made it the ideal travel amplifier.

Why We Like It

The MV50 is a beautiful mini-head with some excellent engineering. This helps it to hold its own in the heavy rivalry in the world of mini amps.

The power section of Class D makes it capable of being compatible with powerful amp cabs, and you can practice quietly with the headphone output.

With only two dials, the variety of sweet British tones you can achieve is commendable. We can't get our heads around the sound that comes from something that's so freaking tiny.
