Are you a guitarist wondering what a preamp pedal is and whether you should try one in your rig? 

In this blog post, I’ll explain what a guitar preamp pedal is, how it works, and its benefits. I’ll also provide tips for choosing the right preamp pedal for your needs.

What is a Preamp Pedal?

A guitar preamp pedal is an effect pedal that helps shape your guitar signal before it reaches your amplifier. It is an important part of the signal chain because it can significantly affect how your guitar sounds.

A preamp, short for preamplifier, are popular guitar pedals that amplify a weak signal from a guitar or other instrument and prepares it for further amplification. It is typically the first stage in a signal chain and helps improve the signal’s tone by boosting certain frequencies and reducing noise.

Many types of preamps exist, including tube, solid-state, and hybrid designs. Each type has its own unique characteristics and can produce different tones. For example, tube preamps are known for their warm and rich sound, while solid-state preamps are often more neutral and transparent.

How preamp pedals work

A preamp pedal is essentially a standalone preamp that you can use in your signal chain instead of the preamp section in your amplifier. The majority of preamp pedals use circuitry that mimics particular tones, such as a tube amp.

The signal flow through a preamp pedal is similar to that of a regular preamp. The guitar signal enters the pedal through the input jack, passes through the preamp circuitry, and exits through the output jack. Some preamp pedals also have additional controls, such as EQ and gain, that allow you to shape the tone of your guitar further.

A preamp pedal offers several benefits compared to the built-in preamp in your amplifier. For one, it allows you to easily switch between different preamp sounds without swapping out amps or adjusting settings on your amp. It also gives you more control over your tone since you can adjust the preamp’s settings independently of your amplifier’s settings.

The Benefits of using preamp pedals

There are several benefits to adding a preamp pedal into your signal chain.

First and foremost, preamp pedals can help you shape your tone in ways that might not be possible with your amplifier’s preamp section. For example, you can use a preamp pedal to add more gain or distortion to your signal or boost certain frequencies lacking in your tone.

Another benefit of preamp pedals is increased flexibility in your signal chain. You can easily switch between different preamp sounds to find the perfect tone for a particular song or style of music. Additionally, you can use a preamp to drive other effects pedals in your signal chain, such as a delay or reverb pedal.

Finally, preamp pedals are generally more portable and easier to use than full-sized amplifiers. They can be easily transported to gigs or rehearsals and don’t require much setup time.

Choosing the right preamp pedal

When selecting a preamp pedal, there are several factors to consider.

First, you’ll want to consider the type of preamp sound you want. Do you want a warm, vintage, modern, aggressive sound? Different preamp pedals will offer different types of sounds, so it’s important to research and listen to demos before purchasing.

You’ll also want to consider the controls and features of the preamp pedal. Does it have an EQ section? A gain control? A built-in effects loop? These features can greatly affect the flexibility and usefulness of the pedal.

Finally, you’ll want to consider the brand and model of the preamp pedal. Some popular brands to check out include Mesa/Boogie, Tech 21, JHS, Fender, and Ampeg. Some popular models include the Mesa/Boogie V-Twin, the Tech 21 SansAmp, and the Ampeg SCR-DI.


A guitar preamp pedal is an important part of the signal chain that can greatly affect the overall sound of your guitar. By using a preamp pedal, you can shape your tone in ways that might not be possible with your amplifier’s preamp section, and you can enjoy increased flexibility and portability.

When selecting a preamp pedal, be sure to consider the type of sound you’re looking for, the controls and features offered, and the brand and model. With the right preamp pedal, you can take your guitar tone to the next level.
