ZT Amplifiers

ZT amplifiers is a really young American company, that manufactures audio equipment. Enginners of Zt are nor afraid to experiment, so some of their products are really unique. As they claim themselves, products of ZT amplifiers are “The loudest small amplifiers in the World”. Let us find out whether this statement corresponds to the reality, by reviewing ZT Lunchbox – one of the smallest amplifiers.

Physical Characteristics

First things first, let us learn the very basics about this amplifier. Knowing the weight, the dimensions and the durability will come in handy while planning your studio.

The WeightZt Lunchbox weighs 12 pounds (which is a little less than 5.5 kilograms). It is indeed a compact amplifier, which everyone can handle.
The DimensionsThe dimensions correspond to the size perfectly, resulting in having a really compact and leight-weighed amplifier.
The MaterialThe material is pretty default. The body is performed of thin plywood, the front panel (where the speakers are) is covered with metallic grille. There is a really durable metallic handle on the top though, which improves the comfort levels a lot.

So now, that you imagine how much place is required for putting this thing down and how much strength you need to apply to carry it, let us proceed to looking at the parameters, that are directly involved in producing the sound.

Technical Characteristics

Mini devices are usually the cut-off versions of their parent devices. This is just the case. ZT Lunchbox Acoustic looks exactly like the child of ZT Classical amp:

Speakers

This amplifier has a single 6.5 custom-designed speaker. The developer says, that it has some sort of unique construction, which makes the sound really loud. Well, we`ll find it out later.

Remember:The amplifier works with 75 Watt of power, has an A/B construction and go as loud as 114 DB (like the subway train).

Inputs and outputs

There are two outputs: one for the speaker, and one headphone output. Sound isolating is by far the best learning practice, so I approve this construction. There are four inputs: ¼ instrument channel, ¼ and XLR mic channel, the power cable input and an auxillary one, for connecting all the devices. Wide variety of inputs makes it possible to create a lot of combinations, which is nice noth in terms of performing and practicing.

Controls

ZT Lunchbox has two independent channels, each of them has following set of controls: Gain, Bass, Treble, Reverb, Volume, AntiFeedback, phantom power and mute switch. If you enjoy adjusting things, you`ll have a lot of fun with this one.

The Features

The last thing before testing the sound is checking the features, that the developer himself thinks are the most outstanding. Here is what I managed to find:

Switchable power levels

The amplifier can go in 115V or 230V modes. It influences two things, the power of the sound and the amount of consumed energy. The second one isn`t that important though, as the amplifier can only worked while being plugged-in.

Independent control channels

I`ve already mentioned it briefly, but this feature deserves more attention. The combination of high amount of adjustability parameters and possibility to choose the personal options of sound for each channel, make Lunchbox a perfect amplifier for two.

Anti-Clip limiting circuit

This does not have any direct influence on sound quality, however it can once save several hundred bucks. The thing is that this type of build prevents breaking the electronic part of amplifier during energy troubles or intense work. Saying same in more simple words: it is the extra layer of insurance.

Okay. All the theoretical part is behind, time to start doing some tests.

Sound Test

While being great-built and everything, this amplifier still remains a mini-version, which puts certain limitations on it. Although the overall level of sound quality was decent, there were some problems.

Advantages

  • High adjustability and sensitivity
I personally enjoy things like adjusting sound a lot. Doing it with this amplifier is a pleasure. Every knob responses easily and makes sound change exactly as you want it.
  • Loud sound

Well, the engineers did not lie, the sound produced by this amplifier is really loud indeed. It is, according to the feedbacks, is enough for having the full-band rehearsals (including acoustic drums). However, it is still mini, so…

Disadvantages

  • Only good for rehearsals and small performances

It is still a mini-version only, so if you are looking for bigger audience, you`ll definitely need a more powerful and professional device.

Pros
High adjustability and sensitivity
Loud sound
The reverb is good
Cons
For rehearsals and small performances

The first thing I recommend checking is the parent of this amplifier.

ZT Amplifiers Lunchbox.

Before summing things up, let us take a quick look at the full version of ZT amp. The ZT Lunchbox Combo Amplifier is an ultra-compact amp loud enough to gig with that weighs less than 10 pounds. It pumps a ton of power through its 6.5″ internal speaker, and can simultaneously drive an external cabinet.

The Lunchbox amp’s clean tonal palette is versatile enough for rock, blues, jazz, and country players alike. This amp is adored by pedal freaks, and takes a boost/overdrive like a champ. It has all the give and responsiveness of a classic tube amp without the size, weight, and maintenance.

The Lunchbox is used in studio and on stage by high-level pros such as Billy Gibbons (ZZ Top), Nels Cline & Jeff Tweedy (Wilco), Andy Summers (The Police), and Lee Ranaldo (Sonic Youth), and has been a best friend to musicians worldwide who love its versatility and portability.

Here are the most important of its` parameters:

  • 200 Watt power. Almost three times as powerful, as 75W Lunchbox Acoustic amp.
  • Compact Dimensions. While being more powerful, it uses pretty much all the same material, so it is as small and light-weighed as all the other Lunchbox amplifiers.
However, this is not an acoustic amplifier, so keep in mind, that its` functions differ a little.
Pros
Compact dimensions
Great sound
Cons
There is no reverb
Overdrive is weak

Conclusion

So, to finish the review, let us sum up the most important things we found out today:

  • ZT Amplifiers is a young American company, that uses innovative decisions in constructing their products.
  • Lunchbox Series from ZT is a set of compact and powerful amplifiers.
ZT Lunchbox acoustic is a perfect mini-sized amp, however it lacks power for making performances in front of huge audience.

Tip:In case you are looking for something more powerful, check out the other products from ZT. The company has a lot of great amplifiers and audio equipment.

This was it for today`s review. Good luck with mastering the guitar.

    I've recently acquired myself a wonderful amplifter for that I'll share my feelings with you. Everyone knows that among guitarists there is a justifiable opinion that amplifters with a speaker diameter of up to 8 inches are at home, and not at concerts and streets. Because the small diameter of the speaker - poorly transmits a full spectrum of the guitar signal, and the power of the sound itself will be low. But any street musician will tell you that an excellent amplifter for the street - must be sharp and bright to "push" large acoustic spaces. The engineers of the company, having thought over all the nuances of guitar architecture and physics, did something new - high power and small dimensions of the speaker and amplifter now in tandem, in the ZT lunchbox. ZT Lunchbox allows you to connect an external speaker, up to 200 watts. stack, which we actually did. And the result surprised - the stack sounded powerful and dense. Both on pure, and on distortion. "Well, if it's so small, then surely at full power the native speaker will overload and wheeze?". This amplifter - does not wheeze, absolutely transparently playing both at the minimum and at maximum power. And to stand in front of him is not too comfortable, very much he is loud. Working through the "native" speaker, the combo is very loud and bright. If you are still confused by the idea of ​​using this "kid" in concert conditions, we assure you that it already works! This amplifter is used by many street musicians, thanks to its mobility and increased power. He was noticed and in scenic conditions, where he was on par with big stacks, was loud and did not drown in the mix. Join the family of compact amplifter, because behind them - the future.

    Model ZT LunchBox Acoustic is a great gadget, because for its price it has pretty good characteristics. I also want to note that this model I like the fact that it has a beautiful design and that it is convenient to carry, because it is not very heavy.
