Buyer's Guide

Bass onboard preamps are an inexpensive and efficient way to add flexibility and increased control to your bass guitar. If you have doubts about the functionality of bass onboard preamps, you have come to the right place. This guide will clear all your misconceptions and will help you choose the best bass onboard preamps in 2021.

Why Do You Need A Bass Onboard Preamp?

A bass onboard preamp will help you gain more control of the tone of your bass guitar. A lot of bass guitars come with preamps or active electronics that do not allow you to be flexible with your tone and do not give you full control. They may affect the sound of your bass guitar in a negative way and you may end up feeling dissatisfied with your bass guitar. With a bass onboard preamp, you can get your dream tone because it will offer all the tonal shaping possibilities including treble, mid, and bass. If you were previously satisfied with your preamp, but it is now malfunctioning, you need to replace it. Buying a preamp with additional features will be a better idea in this case.

What Are Some Important Factors To Consider When Buying A Bass Onboard Preamp?

It is important to do your research before you buy a bass onboard preamp. When browsing for one, keep these few factors in mind to make the job easier for you.

Size and Shape

The size and shape of the preamp you buy should be compatible with the cavity space of your bass guitar. If it already has a preamp, it will have ample space for another bass onboard preamp. When you are looking for a preamp, make sure your bass guitar has space for the preamp itself, batteries, wires, switches, and potentiometers. Otherwise it will be a hassle to install a preamp.

Battery Voltage

While most preamps come with a 9V battery, some allow you to operate them with an 18V battery. This is an advantage because the preamp with a 18V battery will have a better signal to noise ratio. There will be less disturbance when you boost the signal of your knobs.

Active/Passive Switch

Make sure that the bass onboard preamp you buy has an active/passive switch. In active mode you can use the preamp as usual, but in passive mode you can control the volume but not the tone. This can be useful in some situations. For example, you are performing at a live gig and your battery runs out. With this switch you can switch the preamp in passive mode and keep playing until you can change your batteries in a break.

Pickup Compatibility

Make sure that the preamp you buy can accommodate the number of pickups on your bass. When you buy a preamp that is designed specifically for the type of pickup you have, you will get better results. A general one which can work for most pickup types will not be as good.

How To Install A Bass Onboard Preamp?

You do not need to be a professional tech expert to install a preamp in your bass guitar. All you need is good soldering skills. Most bass onboard preamps you to solder pickup wires to the wiring harness of the preamp. An additional wire may also be needed for the battery box and the jack. Some preamps like the EMG are oriented to be ‘plug and play’. This makes it easier to install preamps because there are built in connections for the pickups to connect with the preamp. However, most of the other manufacturers do not provide this feature. If you are not an expert at soldering, you may need to consider taking your bass guitar to a professional to install the preamp. This will save you time and the frustration of having to figure out which component goes where and having to solder the wires.

FAQs

Do I really need a bass onboard preamp?

This depends on your style of playing and whether you perform live or not. They are useful for their buffering capabilities, boosts, and equalization features. These features are specifically useful for those who perform on live gigs and those who record in studios.

How do I know if the preamp I buy will be compatible with my pickups?

The easiest way to judge the compatibility of a preamp with your pickups is by looking at the frequency ranges. Make sure that the frequency ranges of your pickups match the frequency range of the preamp you buy. Different frequencies may work, but they will not give you the best results.

Can I use a bass onboard preamp offstage?

Yes, of course you can use it offstage. You can enjoy added control and increased flexibility of your tones, which is not possible without installing a preamp. However, if you never go for live gigs, you may not need to buy a preamp. But, if you like the additional control of your tones you can certainly invest in one.
