Benefits That Stand Out

Harmonix Nano is no ordinary pedal that promises the world but gets you nothing in reality. This technically advanced but easily accessible pedal is a great companion to any electric guitar.

This astounding pedal has some extraordinary characteristics that will very likely satisfy your inner rock star’s every need. Here are some of those features that make this pedal unique:

  • It offers true bypass which cannot be said for all other pedals in this range.
  • Super fine “Spring” reverb and a flawless and polished “Hall” reverb are available.
  • ​Flanging is fused with a spatial, 3-D reverb in the flerb mode; allowing you to produce a completely unique unearthly sound.
  • ​Packed with a power supply of 96DC-200BI ensuring proper power input.
  • The price is quite reasonable , especially considering the quality.
  • Very sturdy for such a small thing; made in USA after all!

The Salient Features

Like most other pedals, the HG Nano boasts of having a lot of features, but not all of them are designed to be mind-blowing. But according to our test run, we found that the pedal does have some unique characteristics that will make you mull over your decision of getting this pedal over others.

To be honest, we did try out quite a lot other reverb pedals in this range, but we never quite got the satisfaction that we found with this one.

Therefore, we would not shy away from admitting that The HG Nano Reverb is a lot better than others in this league. Here are some of its salient features that made it special to us:

  • This pedal has a befitting design that makes it very easy to use, whether you are a professional or a newbie just starting to feel the vibe of electric guitar effects.
  • It produces truly excellent ”spring” reverb, especially compared to other pedals.
  • The price is relatively low. For all the great features it comes with, the price is relatively low.
  • Power supply is included in the package.
  • This light and small pedal is easy to carry around.

Pros and Cons

While we can very confidently claim that the Harmonix Nano is an excellent pedal, it still has its downsides. Although, they are very few – thanks to its US makers.

However, there is also this possibility that the features that we are taking as downsides are just may be the ones that fall within the category where the features that work great for others may seem to be “not that great” to you.

Still, we would offer you to maintain caution before you buy it. It is always better to look a bit more into something before taking the dive, and in case of Harmonix Nano, we would suggest you to get to know the features and issues that lies with this pedal before you make your move.

In other words, try to find out whether it would satisfy your needs. After all, you are the one who plays the guitar. If you don’t like your pedal, all the positive reviews in the world will be of zero help to you.

So, what better way is there to give you a list of the pros and cons of this HG Nano Reverb to help you decide? Let’s look at the pros and cons of this pedal.



Product Manual

Harmonix Nano is a compact digital reverb guitar pedal that is small, light and easy to carry around. The pedal’s measurement is 7.8*4.3*4.3 inches and weighs just 10.6 ounces.

It operates on 9.6 volts, and has a design that maximizes its potential as it can be placed on the pedal boards without a hitch. The pedal is also very easy to use, if you just know some trick.

For example, upon trying it out, we did find out that the pedal produces this archetypal spring reverb when you are setting the knob to 9’oclock. Turning it to the point of 2’oclock is also okay, but after that you will feel the sound is giving this digital vibe, which you wouldn’t want to hear.

We also did find out that if you decide that you require more reverb, then you can switch to the hall reverb mode. That also produces a good reverb with quite a massive effect as well.


While we researched on Harmonix Nano, we did face many questions coming our way regarding this pedal. We also found some common questions that people ask about this pedal as well. Some of these questions are listed below:

Will the power supply be included with my purchase?

How long the pedal is likely to last?

Is it easy to carry around?

How much electricity does the pedal need to function?

Is the 9.6V adapter included in the package?

  • First of all, do not forget to dust it on a regular basis. A clean, well maintained pedal will go a long way.

Our Advices

So that pretty much concludes our review of Harmonix Nano Reverb pedal for today. After going through the pros and cons that the pedal comes with, we feel that it is a good buy for any guitarist – especially for the mid level guitar players.

However, considering the splendid spring reverb that it produces, we do feel that anyone with a liking to this particular effect would feel lucky to have it in their collection.

Plus, there is also the issue on the price – as this sort of pedal is hard to imagine being available at this price range. Recommended!
