Best Bass Guitar Preamp

A good bassist knows that your tone is definitely something worth being meticulous about, and there’s no better way to get a really great-sounding signal out of your instrument than by running it through a bass guitar preamp. This unit can be used to simply boost the signal, or shape the tone further via EQ, compression, and effects. Bass preamps come in a wide variety of shapes, sizes, and types, from units that integrate into amplifier heads to rack systems. We've chosen the best bass guitar preamps, each one listed here featuring a drive control that allows you to add some grit to your signal, EQ settings that give you the ability to shape the frequency of your bass signal, and they all offer footswitch options to give you hands-free control over your sound while playing, whether it’s through the product’s pedal status or additional footswitch for the rackmount devices.

Eden WP-100 Navigator Bass Preamp

Eden’s WP-100 Navigator bass preamp is a flexible tool that can be used both onstage and in the studio. A studio-quality compressor offers threshold and ratio controls, alongside tube and enhancement knobs to give you even more control of the character of the signal. The EQ here is semi-parametric, which gives you a wide range of directions to go in when manipulating the frequencies of your bass guitar. A footswitch also allows you to control the enhance, compressor, mute, and turbo boost features, making this ideal for gigs where you can’t necessarily turn knobs while playing. The unit also features a DI output control in the front, as well as outputs for both stereo and mono XLR.

Tech 21 SansAmp RBI Bass DI Preamp

The Tech 21 SansAmp RBI rackmount bass preamp opens up a world of possibilities for the bassist who needs a variety of tones to choose from. The preamp’s drive enables users to crank the gain/overdrive in their signal, while presence coaxes out the attack and harmonic content in the upper register. The RBI also comes with a dedicated Mid control to give you a tighter handle on the meat of your tone. The preamp’s Blend feature allows you to mix the direct signal from your bass guitar with the RBI’s SansAmp Tube Amplifier Emulation circuit. Also included is an Effects Loop, along with an accompanying 50/50 switch that allows you to configure that input in series or parallel.

Radial Engineering Bassbone V2 Bass Preamp and DI Box

Whether you’re a regularly gigging bassist or a studio session player, you know that it’s important to be able to capture a variety of tones in your performance. The Tonebone Bassbone V2 bass preamp is designed to do just that, with two channels that each feature their own powerful EQ settings and level controls. The preamp’s 3-switch stompbox design makes it easy to jump between channels as well as the control effects loop and boost. The Bassbone V2 also comes with a built-in DI, making it ideal for live and recording environments. The unit’s separately buffered tuner output works in conjunction with a mute footswitch that makes it easy for you to tune your instrument while onstage without letting the audience hear the process.

Radial Tonebone BassBone OD

Tonebone’s Bassbone OD bass guitar preamp provides two channels that you can use in one of two ways; you can run two separate bass guitars through it, or you can opt with one but have an instantly-switchable A/B setup for your sole signal. The unit features a bass overdrive effect that allows you to dial in just the right amount of bite to your tone. The OD’s drag control and PZB booster provides a variety of resistance levels which make it work well with whatever kind of bass you could imagine using with this preamp, including vintage instruments, acoustics, and other low-output axes. An 1/8 inch headphone amp has its own dedicated volume control, so you can still be in practice mode and sound great. The Bassbone OD has won over some of the premier bassists working in the industry today, including Rhonda Smith (Prince, Beyonce), Carlos Puerto (Chick Corea, Herbie Hancock), and Justin Meldal-Johnsen (Nine Inch Nails, Beck).

Ampeg SCR-DI Bass Multi-Effects Pedal

Ampeg’s SCR-DI bass preamp pedal provides a quick and easy way to dial in the refined bass guitar sound that bassists have looked to the company for over the last few decades. Like all preamps, this unit has EQ and tone controls that allow you to fine-tune your signal till you hit the sweet spot. What sets the SCR-DI apart from the rest is its Bass Scrambler Overdrive, which can be used in a variety of ways; a tiny bit of drive brings out some subtle upper-level harmonics, while cranking it all the way up can result in some grinding, alt-rock sounding bliss. The unit also comes with an 1/8” aux input so that you can play along with signal routed from your computer, mp3 player, and more.

Sean Kramer
I'm a guitarist/music producer with 18 years of experience playing on-stage, in the studio, and everywhere in between. I have toured and recorded on projects both independent and major, in styles such as rock, pop, funk, hip hop, electronic, and more. My axe of choice is probably always going to be the Fender Stratocaster, but I've been known to pick up other guitars when the music calls for it. I'm a big fan of using a multitude of effects (both hardware and software-driven) to manipulate the sound and atmosphere of an instrument. In addition to playing on records, I have also contributed to the score/soundtrack for shows and spots on MTV and ESPN, as well as for a variety of independent films, web series, and television shows.
