Best Guitar Reverb Pedals – 2021 Complete Review

| Last Updated: May 6, 2021

As a guitar player and a good listener, you might have noticed that our surroundings are musical.

You can now embrace this advantage and add reverberations to your tones using the reverb pedals.

Keep reading to find out what reverb pedals are, what they do, our top picks, and much more. 

What is a Reverb Pedal?

Like all the other pedals, a reverb pedal will allow you to add effects to your performance and tweak the sounds to your liking. This device goes next to your other pedals, in the effect chain on your pedalboard, and allows you to add reverberations into your performance. 

What Does a Reverb Pedal Do?

This tiny device allows you to integrate everyday reverberations into your sounds. A reverb pedal combines controls such as effect ratio, decay time, pre-delay time, and tone to simulate the conditions of any room. Or, to be more specific, it can make it sound as though your instrument is anywhere in the room. 

Characteristics of our Favorite Models

There are so many reverb pedals available on the market today – but which one is the best? Here’s a short intro on what matters to us: the uniqueness it brings you, the versatility, and, of course, all of this in an affordable package. 


Most reverb pedals allow you to recreate the usual surroundings – room, hall, cathedral, and others. What makes your sound different from other musicians is, however, the fact that you are unique and have your own playing style, or aim to develop one. Having a pedal with a unique circuitry means the sounds will also be unique. 


Another important characteristic of our models is versatility. A pedalboard is quite limited or may even be crowded. So having an effect pedal allows a lot of freedom, gives a great advantage, and also frees up additional pedalboard space we can use for other accessories. 


Overall, we need the previous two characteristics at a price that will not break the bank, yet the product still needs to be qualitative, unique, and extremely versatile. Have a look at the next section to find out which products on the market meet these three criteria.

Best Overall:
MXR M300

MXR Reverb Guitar Effects Pedal (M300)


  • Great for experienced players
  • Natural and crystal-clear sound
  • Simple, easy to use, and durable built
  • Does not diminish the volume of the signal
  • Encompasses a range of six styles: plate, spring, epic, mod, room, and pad


  • May be considered pricey by some

What Recent Buyers Report

This reverb pedal performs great without diminishing the volume of the signal. All six reverb styles are worth exploring deeply and they can save space on the pedalboard, considering that only one pedal is used for different reverbs. The build is simple and easy to use, yet sturdy and durable. This pedal is great in complementing tones.

Why it Stands Out to Us

The MXR M300 Reverb Pedal is a masterfully crafted device. It contains a range of six high-end reverb styles and each style has rich details and can be easily triggered by the tone knob.

Who Will Use This Most

This pedal is a great choice for anyone looking to complement their performance and tones. With a range of six different reverbs, this can offer you a wide area for experimenting and tweaking. It is a simple to use, high-end pedal, so this product might be best for intermediate players.

Bottom Line

Overall, the MXR Reverb Pedal is a great option if you are looking for a durable 6-in-1 reverb pedal that will allow you to complement your tones to a great extent. Although pricey, this pedal is a true investment for the experienced musician. It is durable, easy to use, and definitely worth every cent.

Electro-Harmonix HOLY GRAIL NANO

Electro-Harmonix HOLY GRAIL NANO Reverb Pedal


  • Easy to use
  • Sturdy, long-lasting build
  • Three reverb modes, from classical to modern
  • Makes tones bigger and more powerful, not louder
  • Minimalistic design, ideal for a crowded pedalboard


  • Can use only its own power supply
  • Longer tail sound compared to others (cannot be adjusted)

What Recent Buyers Report

This beautiful reverb brings distinct sounds in all three algorithms, allowing you to explore classic and contemporary and everything in-between. The pedal is minimalistic, perfect for a crowded pedalboard. The main drawback of this pedal is that it can only be used with its own power supply.

Why it Stands Out to Us

This pedal is indeed the holy grail in terms of reverb pedals. It comes with three different algorithms. The spring reverb recreates the beauty of the classic reverb, the hall option brings lush reverbs, and the flerb is an innovation that encompasses the notions of contemporary, new, and creative sounds.

Who Will Use This Most

This reverb pedal is ideal for anyone looking to enhance and personalize their performance. The versatility of this product makes it the perfect choice for any kind of musician or playing style. It works best with an electric guitar but can be used for numerous other instruments.

Bottom Line

Overall, this is our runner-up for the best reverb pedal out there. If you are looking for a tiny, yet strong and powerful pedal to add some personality to your performance, this is the best choice. The main drawback is that it cannot be used with any power supplies, other than its own, which is included in your purchase.

Best for the Money:
Fender Marine Layer

Fender Marine Layer Reverb Pedal


  • True bypass
  • Great value for money
  • Comes with LEDs for visibility in low-light settings
  • Many additional controls for attack and other settings
  • Makes the tails fade smoothly and naturally after the effect is muted


  • Quite bulky product
  • More complicated to use due to many controls available

What Recent Buyers Report

What makes this product truly shine is the high degree of control it gives to the player. The range of three knobs, volume, tone, and fuzz allows you to control just about everything, but also offers you the chance to shape your music the way you desire, matching it to the equipment you use.

Why it Stands Out to Us

This reverb pedal offers great value for money and comes with a range of three reverbs. Similar to our other picks, it comes with natural reverb types, room and hall, but also combines modernity in the shimmer reverb type. In addition to this, the reverb tails fade out naturally and smoothly when the effect is muted.

Who Will Use This Most

This reverb pedal is suitable for intermediate players and up. The pedal comes with quite a few controls, apart from the usual ones, such as bloom (controlling attack), mod switches for extra thickness or low end, and many others. Additionally, this pedal comes with an extremely competitive price, making it affordable for anyone.

Bottom Line

Overall, this pedal offers great advantages and control, but you need to be cautious if you have a crowded pedalboard, as it is quite large and bulky. It comes with many features, giving you greater control over your performance. If you usually play in low-light settings, this pedal with LEDs will be quite an asset.

Best for Acoustic Guitar:
Caline CP-26

Caline CP-26 Snake Bite Acoustic Guitar Electric Effects Pedal Reverb Delay Digital Analogy Multi Distortions True Bypass Black


  • Extremely affordable
  • Good-quality and versatile
  • Best pedal for acoustic guitars
  • Great for practicing, beginners, and novices
  • Comes with numerous controls, including resonance, center frequency, low pass filter, mix, decay, and others


  • Design tends to look tacky

  • Might take some time adjusting and tweaking to get the right sounds

What Recent Buyers Report

What is really great about this pedal is its low price. Additionally, it seems that the pedal works a thousand times better than it looks, compared to the price range. If you have an acute need for a good, affordable reverb pedal, this is the best choice. It offers decent control over the tones.

Why it Stands Out to Us

This is our top choice for acoustic guitars, which includes the usual control knobs, such as mix, decay, and pre-delay. Additionally, this pedal has its own unique circuitry, with the "res" knobs and "CFR" and "LPF". These control the resonance, the center frequency, and the low pass filter, giving you a wide range of choices to spend some time exploring.

Who Will Use This Most

This reverb pedal is great for any beginner or hobbyist musician. Within an extremely low price range, this pedal offers decent control over the tones and quite a few features which need to be explored. On the other hand, the design is not really an advantage and it tends to be quite noisy if mix and decay are turned all the way up.

Bottom Line

Overall, this pedal is a great choice for any aspiring musician. It can be a great starting point if you want to dive into the endless universe of guitar effects. It might not have all the features more expensive products have, but this can be quite an advantage if you are a beginner looking to learn your way around effect pedals.

Editor’s Pick:
Fender Tre-Verb

Fender Tre-Verb Tremolo/Reverb Pedal


  • High-quality and sturdy design
  • Easy to use and extremely versatile
  • Optical, Bias. and Harmonic Vibrato as tremolo modes
  • Tremolo and reverb can be combined or used independently
  • Classical reverb voices, including ’63-’65 spring and plate, plus ambient variations


  • Quality control

What Recent Buyers Report

This great pedal does everything a high-quality device needs to achieve. You can achieve either subtle or bold sounds, but also everything in-between. The design is sturdy, long-lasting, and, although it comes with many knobs and functions, it is quite easy to use.

Why it Stands Out to Us

Fender Tre-Verb is our last pick for great reverb pedals, yet it is the first choice for many musicians. It comes with two independent effects, tremolo and reverb, but they can also be used together to generate intriguing tones. The tremolo modes are all classical, such as optical, harmonic vibrato, and bias, while the reverb is ’63-'65 spring and plate, along with their ambient variations.

Who Will Use This Most

This practical pedal combines both tremolo and reverb, so if you are a fan of both, you should definitely check it out. This pedal offers you the opportunity to stand out from the crowd by using two effects in only one pedal, which can be combined to create unique effects or can be used separately.

Bottom Line

Overall, the Fender Tre-Verb is a great choice for any musician. It comes within an affordable price range and is incredibly versatile. The best feature of this pedal is that it allows you to be unique and creative, due to the combination of tremolo and reverb.

Types of Reverb Pedals

Reverb pedals are quite varied. The most common types of reverb pedals include:

True Spring Reverb

The spring reverb is called so because it does use a spring to generate the sound. This works as the audio signal is sent to the spring, which will start vibrating and make the reverb sound as the signal goes down the spring. Most products today have found innovative ways to achieve this using modern tech, such as the emulator spring reverb, which uses digital circuitry to recreate the sound. 

Multi-Mode Reverbs

This is the most common type, which you will find above. The multi-mode reverb pedals combine different reverbs, such as room, shimmer, hall, or plate, all included in a tiny circuitry, allowing you endless opportunities and versatility. If you are looking for variety, this is the type for you. This type allows you to dial in almost any reverb effect in existence and will enable you to create unique combinations. 

Ambient Reverb

If you are a doom metal player or shoegaze, the ambient reverb allows you extended decay times and the possibility to add layers of other mod effects, such as pitch shifting and delay. If you are into experimental music, the ethereal effect is the best choice for you. 

How to Use a Reverb Pedal

Here’s a shortlist of steps on how to use your reverb pedal and make the most out of it:

  1. Decide which setting you prefer. If you are unsure, you can try all of them to check out what fits you best. Once you decide which one is for you, remember to use it for the next step. As a short guide, your pedal may have a spring effect, which is the least strong effect, while the strongest is cathedral. If you are looking for a medium reverberation, you might want to check out room and hall. Some pedals include the plated effect, which is quite metallic – you should also use long decay with plated settings.

  2. Dry or wet signals. In the next step, you should decide how wet or dry the signal is. You can achieve this by using the knob allotted to it, which is usually noted FX or Reverb. 

  3. Tone knob. Some pedals with tone knobs will allow you to adjust the warmth of the sounds. Tune the quality of the sound to your liking. This helps, especially if you are after an intimate atmosphere.

  4. Adjust the decay. The decay knob will control the length of the sound and should be paired with the setting. As a short guide, room goes well with a quick decay, while church or cathedral go better with longer decays. Generally, a long decay means more reverb. 


Overall, reverb pedals can be true heroes if you want to establish a particular atmosphere. They are affordable, easy to use, and quite simple. There is no actual reason you should not have a reverb pedal on your effect chain. 

People Also Ask

There are quite a few mysteries surrounding effect pedals, mostly because classical guitar players do not typically benefit from the technology of today. Here’s a short FAQ section to clarify some aspects. 

Do I Need a Reverb Pedal if My Amp Has Reverb?

This largely depends on your needs and preferences. If you are content with your amp’s spring reverb, you might not need a reverb pedal, although you should explore your options before making this decision. On the other hand, you should purchase a reverb pedal if you want a stronger reverb, such as cathedral, hall, or plate effects. 

Does Reverb Make You Sound Better?

A reverb pedal is quite useful to recreate certain settings when you miss them - if you want an intimate atmosphere or a stronger reverb, such as a church. A reverb pedal allows you control over these settings and improves the sound. It is highly recommended you explore this option - you might be surprised at the change. 

What is a Shimmer Reverb?

A shimmer reverb has become more and more popular, and it is an ethereal, unearthly, string-like reverb which is layered underneath the guitar’s regular signal.
