Let’s be clear: If you know anything about guitar playing, you’ll know the harmonica is achieved by minimal effects. Because it already boasts a rich timbre sound, it doesn’t take much to achieve that indistinct and muddy sound.

If you’re new to harmonica playing the first thing you’ll need is a good reverb. If you’re unsure which reverb to pick, we made a couple of recommendations below. You might find one that suits your needs and preferences.

So before making this investment, make sure you play it at full volume. Only then will you know whether it’s the best effect pedal for harmonica in your unique application, or not.

We’ll discuss a few pedals including their individual specs and features. All you have to do is pick the one that works for you.

TC Electronic Nova Effects Pedal

Here we have a unit designed to serve most requirements of a modern guitar player. It stores up to six stereo delay types for your convenience. Not just any delay types but they are studio quality. Because of this feature you can create a wide range of unique sounds. However, note it doesn’t have the looper function, only the delay.

You also have the option of storing up to nine customizable presets. The best part is they’re user programmable. The only downside is you have to go through all of them if you want to change settings. Plus switching between presets can be tricky making it pretty time consuming.

Another useful feature you’ll like is the preset and manual mode. These allow you to interchange between the necessary settings for that desired sound effect.

The unit weighs only 1.7lb making it very portable. It features a compact floor-based design for your added convenience.

You’ll also like the versatile tap button which also acts as a mute button: Simply press it for a couple of seconds. Together with this unit you’ll find a power cord to plug it in since it’s not battery operated. The novice guitar player will find it slightly difficult to learn initially. However, it’s relatively simple to operate once you master it.

Though it comes with an instruction user manual, people have noted the manual is a bit vague. It doesn’t adequately describe how to adjust certain parameters. You can consider downloading one of the product documents found on the company website. It has more detailed and easier to understand instructions.

The LED display makes it easier to dial in a tempo. Overall, this pedal produces a good range of sounds you’ll like. And for the diverse functions it offers, it comes at a reasonable price.

Electro Harmonix Holy Grail Max Reverb

The Holy Grail Max reverb is the ultimate portable pedal for the guitar player lover. This unit comes with a combination of four reverb types to enhance your musical experience. These include the spring, hall, plate and reverse reverb. You’ll enjoy a unique lush tone thanks to the plate reverb. The reverse functionality is for the guitar player looking for a more sonic sound.

It allows you to adjust the timing and mix of each reverb. This way you can customize the sound to your exact preference. With this unit you’re able to adjust decay or reverse time using the multi-function control.

It features true bypass which is designed for maximum signal path integrity. The blend knob allows you to adjust the reverb until you get the exact sound you want.

Unlike other guitar effects pedals, stepping on this pedal won’t decrease the volume. On the contrary, it adds a layer of reverb on your tone which sounds great. For a clearer sound we’d recommend that you put all your distortion before the reverb. Distorting the reverb will just make it sound muddy.

Want to perfect your vocals?  Not only does it enhance sound effects, it’ll work particularly well for smoothing out your vocals. A beginner will definitely find the device easy to use.

For the sound it produces you’d expect it to be large and heavy. But it’s quite portable; double the width of a micro effects pedal. The package also includes 9.6DC – 200 power supply for connectivity purposes. However, you can still use batteries to power it up though which you can purchase separately.

It’s guaranteed to last long thanks to the compact and rugged die cast chassis. The solid metal construction also ensures longevity.


  • Acts as a noise suppressor
  • Very easy to use
  • Sounds great
  • Clear and noise free output
  • Solid build
  • Impressive range of tone and control

You’ll agree the best effect pedal for harmonica for a beginner must be affordable while not compromising on performance. This model ticks both boxes and more. The product comes with an expression pedal. It can be used to control up to three parameters in real time to get the sound you want.

By adjusting them you’ll achieve the exact sound you want. It’s a versatile product best suited for both warm classic vocals as well as cutting edge distortion. You can also use it for those Lo-Fi styles.

The exclusive voice feature transforms your voice depending on your preference.

It features up to 38 studio quality effects which are fully programmable—up to seven effects at once. A novice guitarist will find this easy to operate thanks to the intuitive user interface. The interface features six character alphanumeric plus two-character numeric displays. These characters together with the four-knob matrix system make it simple to use.

It includes 40 factory and user presets enabling you to customize your musical creations. With this unit you can also sing along to your favorite song. This is made possible by 1/8” CD inputs located on the rear panel.

For that balanced sound, the model comes with a ¼“ unbalanced input and a balanced XLR mono output. Also, the ¼“ TRS stereo line output and 1/8” headphone output also ensures you achieve that right unique sound.

One of its major downsides is the pedal doesn’t have a noise gate. Because of this you’ll get annoying and noisy feedback at certain volumes. As a result, we wouldn’t recommend it for live performances—just studio use. However, with time you’ll figure out the right effect which minimizes feedback.


  • Reliable
  • User friendly
  • Polished sound
  • Easily programmable
  • Enhances voice quality


  • Noisy
  • Not for live performances
  • Too many editing commands

Electro Harmonix Deluxe Pedal XO

This is one of the most popular analog delay devices on the market. You’ll enjoy a unique organic sound thanks to this model. It produces up to 550 mS of vibrant echo, you won’t experience any tape delay.

It features a wide range of sounds you’ll find useful. Sounds produced include the spatial chorus and the haunting vibrato to mention a few.

It comes with a number of knobs to help you achieve that perfect sound. The blend control knob enables you to vary and tweak a different mix of direct and delayed signals. This is achieved by setting it to the center position.

The level knob also allows you to control the overload LED. It’ll blink on the louder notes you play; however, the lights won’t be too bright or frequent. This not only reduces distractions caused by a blinking light, but distortions are eliminated.

Another knob you’ll find particularly useful is the feedback knob. It allows for delay repeats or multiple echoes depending on your preference. However, it’s important to note that setting it too high will cause runaway oscillation. On the other hand, moderate feedback with short delay will result in a reverb effect.

This unit also allows you to control the speed of the chorus by using the chorus or vibrato knob. With this knob, it adjusts the delay time accordingly. It’ll go slower for the chorus and faster during vibrato.

It also features a depth knob to control the amount of modulation during delay time. The delay knob determines the time that lapses between the delayed and direct signals. The same feature also picks up on the time between the repeats, particularly when feedback is used.


  • Impressive analog delay
  • Reasonable price
  • Produces organic sounds
  • Very responsive
  • Noise free
  • Clean output
  • Durable

Danelectro D4 Fab Slap Echo Effects Pedal

As a beginner in guitar playing, a product that makes mastering your skill easier is the one you want. For that reason, we recommend this easy to use Slap Echo Effects Pedal from Danelectro.

It features a number of intuitive controls such as the repeat and mix tone functionalities. With these two you can alter, mix and adjust the sound till you get the desired effect. The only downside is adjusting the repeat button produces a noisy sound.

To power it up you can either use a nine-volt battery or nine-volt adapter. The batteries are included in the package for your added convenience.

What is also important to note is this is a digital pedal not analog. This means you can use it with a delay digital chip. Also, though it sounds great we wouldn’t recommend using it as a reverb. This is because it produces more subtle sounds and effects.

It weighs 8.8lb making it a relatively heavy unit. The model comes in orange if you like that particular color.

What we don’t like regarding its construction is the pedals are cheaply made making their durability questionable. Try to use it with caution as it won’t handle prolonged abuse. You can consider re-housing it in a metal box for added durability.

One of the unit’s major concerns is it uses a lot of power. When operating it using batteries they won’t last as long as you’d want. To avoid this, make sure you unplug the input to completely switch off the power from the circuit. Leaving the input plugged in when it’s not playing will just drain the battery as it’ll still be powered.

If you’re a beginner, you’ll appreciate this pedal which features a very simple design. It’s a pretty basic digital delay unit which is priced reasonably. Plus, it’s super easy to use. As mentioned, the only issue you might have to deal with is its durability.


  • Affordable price
  • Easy to use
  • Fast shipping
  • Simple and intuitive controls
  • Excellent for modding  


  • Durability of pedals questionable  
  • Repeat button noisy

Also, the pedal you pick must produce good stereo quality sound. In addition, it must offer more versatility to allow you to experiment with different sounds.

You might want to go for the pedal which is also easy to use. Picking one that’s complicated to learn will just further delay your guitar learning abilities. Hopefully at least one from the five mentioned above matches your taste. If you have more questions though, please leave a comment below.
