Preamp Pedals for Bass: Buyers’ Guide

In this buyers’ guide, we’ll provide you with the information you’ll need to make an informed decision when purchasing a preamp pedal.

What Does a Bass Preamp Pedal Do?

The functions of a bass preamp pedal are closely tied to the construction of your typical amplifier. As you may or may not know, an amplifier is put together in two distinct stages, the preamp and the power amp stages.

A bass preamp pedal also shares these two sections when it comes to its functions. In the preamp section, most of the signal from the instrument is processed in order to convert it into the distinct sound of the amp; these are known as preamp pedals, as the processing is done before (pre) it gets to the amp.

Next, it hits the power amp section where the signal is considerably amplified before it’s sent towards the output, which is usually a speaker.

In the preamp pedal, the first stage or the preamp stage is basically brought down to a foot-pedal to allow the user to control this process with precision; this enables you to control various elements of the overall sound being produced, including changing the tone, EQ, level control, and gain. 

You can use this device to modify and improve the signal before it hits the power amp stage, and the sound is amplified.

Preamp Pedals and Bass Driver DI Boxes

There are tons of similarities between a preamp pedal and a direct inject box or bass driver DI box. Essentially, both devices take your unbalanced signals from your instrument and help you convert it into a balanced output. 

The difference between the two devices comes down to the range of functions made available to the user. A bass driver DI box can only be used to adjust the signal level, and that’s pretty much it. There are higher-end models that have been recently introduced to the market that offer some of the features of a preamp, but this only occurs in the high-end range.

On the other hand, preamp pedals offer the user a wide range of options when it comes to modifying their signal at any price point. It basically works as a foot-operated version of a real amplifier, minus offering an output channel, and this is where the two devices stand out.

Bass Preamp Pedals and Onboard Bass Preamps

If you own an instrument with its own set of bass preamps, you’re probably wondering if you’re really in need of a bass preamp pedal, and that’s a good question.

Not every guitar is gifted with an onboard bass preamp set, and you’re most likely to find this handy addition on high-end models. The functioning of the onboard set will probably be just as good as the preamp pedals on the market. 

The big difference between the two units comes down to your personal tastes and preferences. Your onboard unit may have certain features, but it’s unlikely to have all of them when it comes to modifying signals from the bass. 

Certain EQ functions are only accessible through certain pedals, and they offer you a completely different tone from your existing sounds. Beginners may be willing to settle for the variations on their onboard preamps, but seasoned musicians will still seek greater variations in sounds through the use of preamp pedals.

How to Pick the Best Bass Preamp Pedal

Here are some useful features that you need to keep an eye out for when picking up a bass preamp pedal. Just remember that these are only the features of the pedal. When it comes to picking out the sounds that’ll most suit your music, it’s a subjective experience, and you need to rely on your ear to find the best match for that.

The Big EQ

With the help of an equalizer, you’ll have the ability to radically change the sounds of your instrument using various parameters. While your average foot pedal may not give you a full graphic EQ, you can at least seek out a model that offers you a two-band setup.

Level and Gain

There’s a clear difference between the concepts of level, gain, and volume, and it pays to understand this distinction before picking out a pedal. The gain refers to the input signal level before the device has gotten a chance to influence or affect it in any way.

When you use varying levels of gains on the various preamp functions, it helps you greatly modify your composition’s overall sound; this is where the level function comes in.

The level function allows you to control the various gains going into the preamp for bass, and this will enable you to modify sounds with greater precision.

Blend Feature

This nifty little adjustment allows you to tinker with the signal in order to blend between your processed and unprocessed signals. Thanks to this feature, you get to control just how much of the preamps’ sound you’ll utilize at any given point.
