What is a Preamp Pedal?

A preamplifier (preamp) pedal is used to amplify quiet sounds or signals. These preamp pedals are often used first in effect chains in order to amplify the weak signals coming from passive pickups. Any pedal can be used as a preamp – such as overdrive, distortion, or a chorus pedal, as they can all be placed first in the chain to deal with weak signals. 

While such pedals are quite simple, allowing you simple tone control, a preamp pedal is much more complex than that. It may have switches between different channels and more sophisticated and complex EQ, among others. 

What Does a Preamp Pedal Do?

There are some fantastic uses of preamp pedals, so here’s a short summary:

Adjusting the EQ points

All amps have standard EQ points. A preamp pedal can help you tweak them to adjust the overall quality of the sound. Think about a troublesome venue where the sound is just not right. A preamp pedal will help you adapt the sound to the stage. 

Easily Switch Between Guitars

A preamp pedal is a lifesaver if you often change guitars during a gig. Instead of having to walk to your amp and adjust to the next instrument, you can use the pedal without a fuss to select all the settings in no time. 

Pre-Gain Adjustments

A preamp pedal helps you finely adjust the tones right before the gain and fixed tone – a little EQ tweaking can go a long way. 

Additional gain control will help you broaden the tonal palette and you can switch between the pedal tone and amp tone in the blink of an eye. You can do that at any time, even in the middle of playing. A preamp can add warmth and grit without having to turn up the amp gain. 

Why Did These Pedals Make Our List?

There are so many options on the market – different features and prices can cause a lot of headaches when choosing a preamp pedal, especially when you are not sure what to look for. Here is what we focused on:

Versatility and Controls

Although the pedals are quite varied, we made sure they offered you all the control you need to tweak the sounds to your satisfaction. A good preamp will add a bit of everything so you can easily adjust the tones and add a bit extra to your sound to make you stand out. They are also highly recommended for all guitar players, despite different playing styles or music genres.  

Premium Quality

A prerequisite for making it to our list is, as usual, the quality of the products. Based on a thorough review of these products, the pedals are long-lasting, durable, but also extremely easy to use in any environment, including low-light settings (that’s what LED lights are for!). 

Value for Money

Last, but not least, the quality and versatility of the pedal need to at least match its price. Have a look in the next section to find out how you can get the best out of your investment.

This pedal is not a simple pedal – its best asset is that it improves the overall sound, unlike other pedals, which often only enhance one sound quality. You can add brightness, use it as a treble booster perfect for leads, or you can just go for a tone neutral boost. Whatever you are looking to do, this pedal is worth the effort.

Why it Stands Out to Us

This true bypass preamp pedal offers you four unique preamp voicings, has a body and air fine-tuning circuits, and is highly reliable. This pedal is worth experimenting with; when placed first in the effect chain, you can use the air control to make the high-end shimmer in the pickups stand out.

Why it Stands Out to Us

This studio-quality preamp pedal provides crystal-clear tones and preserves pedalboard space. It has two separate input/output level controls, along with three-band EQ, which provides you with broad tonal flexibility. Additionally, it eliminates hum due to the ground lift for the best performance.

Who Will Use This Most

Bottom Line

Overall, this is built as sturdy as a brick and offers exciting options. Although not as versatile as other products, some might prefer to keep it simple. We believe this would be suitable for many players, but most likely would go hand-in-hand for slap-style bass lines.

Why it Stands Out to Us

It contains three-band EQ, a one-knob compressor, a chromatic tuner, an effects loop, automatic feedback suppression, and an XLR, along with software for ever-expanding instrument images.

Who Will Use This Most

This is highly recommended for acoustic players, especially for stage performers or studio recordings. It takes some experience and patience to make this gear work, although an angel-like, milky sound is definitely one purchase away. It is highly recommended for professional or experienced players.

Benefits of Investing in a Quality Preamp Pedal

Here is a shortlist of the gains of investing in one of our recommended pedals:

Add Some Juice to Your Tone

Our premium quality pedals will definitely add some character to your sounds. They are flexible and highly versatile, offering a broad spectrum of choices to shape the tones. In fact, this is why you should buy one in the first place – to allow you to tweak the tones to your liking. 

Adjust EQ Settings

Another benefit is that a high-quality preamp pedal will allow you more flexibility with the EQ settings. You can either adjust EQ settings for certain songs or just experiment until you find your favorite sound and then keep it on all the time. 

Boost the Tones

As the name suggests, most guitarists use preamp pedals to significantly boost weaker signals. A high-quality preamp pedal can be a lifesaver if you have a low budget guitar, too, or if you often play in venues where you have trouble with the sound quality. 


Overall, we briefly reviewed why you need a good quality preamp pedal and what you get out of it. In the end, one might argue that guitarists quite under-appreciate them since most believe that there is no need for a preamp, since you already have similar controls in other pedals.

People Also Ask

Here is a short FAQ section to clarify some more details about preamp pedals, such as where to place it in the effect chain, how it can improve the sounds, and whether you need one or if it is just optional. 

Where to Put Preamp in Pedal Chain?

The best answer to this is to experiment and find out what you enjoy most. They can be placed either in the front or at the end of the effect chain. As a general rule, you should use the preamp pedal in the front if you want some grit, or place it at the end of the chain to keep its tone-shaping abilities. 

Does a Preamp Improve Sound Quality?

One first obvious benefit of using a preamp pedal is its ability to clean the noise and give you clearer sounds. The preamp will help you improve the sound quality in several ways. Here are the most common issues a preamp pedal helps to solve: thin sound, weak signal, unbalanced signal, noisy/scratch signal, feedback. 

Do I Need a Preamp for Guitar?

A preamp guitar will help you clear the tones and reduce the noise some other pedals might cause. Additionally, you can greatly shape tones to your liking, apart from several other perks. A preamp pedal is not a definite requirement, of course; however, we highly recommend that you try it out – you might be surprised!

What is the Difference Between a Preamp and an Amplifier?

The simple definition of an amplifier is that it amplifies the line-level sound, while a preamp amplifies a weak signal to the line-level sound. A preamp will help you shape and tweak the basic, or core, sound of the guitar through the EQ settings, thus, the preamp does not boost the actual sound – this is actually what the amplifier does.
