Buying guide
By PedalBro · Updated October 16, 2026 · We do not test pedals, here is how we rank them
A bass overdrive needs to add grit without stripping out the low end that holds a band together. When choosing one, look at whether it was designed for bass from the start, whether you can mix in your clean signal, how much tone shaping it offers, and how much board space and power it needs.
The EarthQuaker Devices Blumes is our top pick for most bassists. It is an analog drive built specifically for bass, using a Tube Screamer-type JFET circuit that has been reworked so the lows survive. It offers switchable soft-clipping voicings, sits in the middle of this list on price, runs from an ordinary pedalboard supply or a battery, and fits on a crowded board.
If you want to spend as little as possible, the Behringer BOD400 Bass Overdrive costs among the least here and still gives you a clean blend and some EQ. If you would rather have a full amp-style preamp than a plain dirt box, the Origin Effects Bassrig Fifteen is the splurge, and it has the strongest review behind it.
Top pick · Best for bassists who want a dedicated drive that holds on to the low end
The EarthQuaker Devices Blumes is an analog overdrive designed for bass, with switchable soft-clipping voicings and a circuit tuned to keep the lows full. But we wish more reviewers had weighed in, since few published opinions stand behind it.
Budget pick · A good choice if you want a clean blend and basic EQ for very little money
The Behringer BOD400 Bass Overdrive is among the cheapest pedals here, yet it lets you mix dry signal with the drive and shape the result with a two-band tone section. But we would rather have true bypass and stereo, and it offers neither.
Splurge pick · The step up if you want a full analog amp tone in a pedal and can afford it
The Origin Effects Bassrig Fifteen packs the sound of a classic 15-inch speaker bass amp into an analog preamp with a direct out, and Guitar World scored it 5 out of 5. But we know it costs a lot and takes up far more board space than the other picks.
Who this is for
This guide is for bass players who want overdrive that sounds good on bass, whether that means a touch of hair or a heavier push, while the bottom end stays solid. If you mostly want clean amp tone with a precise EQ, the preamps in the other options below may suit you better. If you need stereo, none of these pedals is listed with it, and the BOD400 and both Aguilar pedals are confirmed mono.
Blend control
A clean blend lets you add dry signal back in so the low end stays firm under the distortion. The Behringer BOD400 and the Boss ODB-3 both list one. The EBS Billy Sheehan Signature Drive goes further, with separate level control over its clean and driven paths.
Overdrive or preamp
Some of these pedals are straightforward drive boxes, such as the Blumes, the BOD400 and the ODB-3. Others, such as the Origin Effects Bassrig Fifteen, the MXR Bass Preamp and the Aguilar models, are amp-style preamps that can also handle clean tone and EQ duties.
Size and power
Most of these draw little current and accept a battery. The Bassrig Fifteen is the exception: it pulls 150 mA, weighs 848 g and is much larger than the others, so check your supply and your board space.
Bypass type
The BOD400, the ODB-3 and the MXR Bass Preamp use buffered bypass, which means the signal passes through their circuitry even when the effect is off. If you want true bypass, check the spec sheet before buying.
How we picked
We looked at every pedal that fits this guide and is on sale new today, then ranked them by what reviewers and buyers say, how many sources say it, and what it costs. The full method is here.
What we do not do
We do not test pedals. Everything here comes from published reviews, retailer ratings and player discussion, so you can follow it back to its sources.
PedalBro is an index of guitar pedals, not a testing lab. For this guide we gathered the published reviews, retailer star ratings and player discussion we hold for every pedal that fits, turned them into a single PedalBro score, and ranked the pedals on that score, how many sources stand behind it and price. A person reads every guide before it is published. 46 pedals fit this guide and 15 of them had a score we could rank.
Best for bassists who want a dedicated drive that holds on to the low end
PedalBro score 77/100 · 1 source, an early read
The Blumes was built for bass rather than adapted from a guitar pedal. Its JFET circuit starts from the Tube Screamer approach and widens the response at the bottom, so you get breakup on top while the fundamental stays put.
It has more voicing options than the Behringer BOD400 Bass Overdrive. Its soft-clipping modes let you change the character of the drive without changing pedals. It also sits in the middle of this list on price, well below the Origin Effects Bassrig Fifteen.
It is easy to fit into a rig. It draws only 25 mA from a standard center-negative 9V supply, accepts a battery, and at 300 g it is the lightest of our three picks.
Reviews are thin for the Blumes. Less published opinion stands behind it than behind the Bassrig Fifteen, so you are relying more on its design than on a track record.
Its spec sheet lists no clean blend, which both the BOD400 and the Boss ODB-3 offer. Players who like to mix a lot of dry signal in may miss that.
Who should skip it: Skip the Blumes if you want a clean blend for the lowest outlay, which the Behringer BOD400 Bass Overdrive provides, or a full amp-style preamp, which the Origin Effects Bassrig Fifteen provides.

PedalBro score 72/100 · 1 source, medium confidence
The main reason to buy the BOD400 is its blend knob. It lets you dial in as much clean bass as you need under the dirt, which is how many players keep the bottom solid.
The BOD400 offers a lot of control for very little cost. Its two-band EQ gives you more tone shaping than many pedals at this price, and its breakup is described as smooth and responsive to how hard you pick. It costs much less than the EarthQuaker Devices Blumes or the Origin Effects Bassrig Fifteen.
It is a low-fuss pedal for a board. It draws 30 mA from a standard 9V center-negative supply, can run from a battery, and has a footprint close to that of the Blumes.
The BOD400 uses buffered bypass rather than true bypass, so your signal still passes through its circuit when it is off. It is also mono only.
It has fewer voicing choices than the Blumes, and detailed published reviews are scarce. It is a good-value tool rather than the most refined option.
Who should skip it: Skip the BOD400 if you want switchable clipping voicings, as on the EarthQuaker Devices Blumes, or you insist on true bypass.
The step up if you want a full analog amp tone in a pedal and can afford it
PedalBro score 85/100 · 1 source, medium confidence
The Bassrig Fifteen has the strongest review of any pedal in this guide. Guitar World's 5 out of 5 verdict praised how well it is made and said its tone delivers what you would expect from a recreation of the Ampeg B-15 Flip-Top.
It does more than add dirt. As an amp-style preamp with voicing modes and a direct output, it can feed a PA or recording rig on its own or slot in front of your existing amp. That same review noted that it works well either way.
Next to the EarthQuaker Devices Blumes and the Behringer BOD400 Bass Overdrive, it is a different kind of purchase. You are paying for an entire amp character rather than a single overdrive voice.
The Bassrig Fifteen is among the most expensive pedals on this list. Even Guitar World, while calling it worth the money, pointed out the high cost.
It is large and heavy, at 91.4 x 147.3 mm and 848 g, and it draws 150 mA, far more than the other picks. Make sure your power supply can deliver that much current.
Who should skip it: Skip the Bassrig Fifteen if you just want an affordable dirt box or need tones beyond its single amp inspiration, in which case the EarthQuaker Devices Blumes is a better fit.
These did not make the top three, but some of them are the right choice for the right player.
If you want separate control over clean and dirty signals: the EBS Billy Sheehan Signature Drive combines a two-channel mixer, a compressor, EQ and overdrive, plus effects loops for each path. Premier Guitar scored it 4 out of 5 and Bonedo 5 out of 5, with Bonedo noting little noise even at extreme settings. It is more pedal than many players need, and Bonedo found the internal battery mount a bit flimsy.
The MXR Bass Preamp pairs a three-band EQ with independent gain and master level, and Premier Guitar scored it 4.5 out of 5, calling it versatile. It is a preamp first and an overdrive second, and it uses buffered bypass, so the Blumes fits this guide better for straightforward drive.
The Boss ODB-3 Bass Overdrive offers a clean blend, a very low 13 mA current draw and a price among the lowest here. The Behringer BOD400 covers the same ground at a similar price, so we picked that instead.
If pedalboard space is tight: the Aguilar DB 925 is a mini-sized preamp with simple bass and treble knobs and a tiny 3 mA draw. Little review evidence stands behind it, and it is more of a tone shaper than a dedicated overdrive.
If clean tone and a detailed EQ matter more than grit: the Aguilar AG Preamp offers a four-band active EQ, and Bonedo scored it 4.5 out of 5, praising its clean sounds, flexible EQ and solid construction. It is costly and mono, and it is not focused on overdrive.
A blend control lets you mix your dry bass back in with the driven sound, which helps the low end stay solid. The Behringer BOD400 Bass Overdrive and the Boss ODB-3 Bass Overdrive both have one, and the EBS Billy Sheehan Signature Drive lets you set its clean and driven levels separately.
Yes, most of them can. The EarthQuaker Devices Blumes, Behringer BOD400, Origin Effects Bassrig Fifteen, MXR Bass Preamp, Boss ODB-3, Aguilar DB 925 and Aguilar AG Preamp all accept a battery as well as a 9V adapter. The EBS Billy Sheehan Signature Drive also has an internal battery mount, though Bonedo found it somewhat fragile.
An overdrive such as the EarthQuaker Devices Blumes or the Behringer BOD400 mainly adds grit. Preamps such as the Origin Effects Bassrig Fifteen, the MXR Bass Preamp and the Aguilar AG Preamp recreate an amp-style front end with EQ and can also handle clean tone. The Bassrig Fifteen also has a direct output for running straight into a PA or recording rig.
Yes. The Behringer BOD400, Boss ODB-3 and MXR Bass Preamp all use buffered bypass, so your signal passes through their electronics even when the effect is off. Check the spec sheet if you need true bypass.
