One of the first you should think of if you want to achieve good sound without annoying your listeners and blowing your speakers is proper bass guitar adjustment. After gain setup, you’ll have to know something about EQing your bass. Things are not that simple as you think. Like, plug the bass, tweak a bit eq knobs and rock on. No, no. That is not how you can achieve the awesome punchy bass sound that moves your chest. First things first, look around you, if you are in the room and there are ceramics, glass, in other words, flat surfaces you or your audio engineer should put a lot of effort to make your sound good enough.

If your stage is outside, there will be also some of the difficulties making a good and powerful sound of your bass guitar. After all, the most important thing is PA equipment on which you are going to perform. You can’t expect loudness and enough power at the low frequencies without mighty subs. Let’s say you have some decent equipment so we can explain to you in following lines in detail on how to EQ and mix your bass guitar for live performance. By the way all of these tips and tricks can be applied in studio mixing and whether you are going to plug your bass directly in mixer or planning to mic the amp. There will also be some crossover with techniques you might use when mixing an electric guitar live or an acoustic guitar.

You can probably find on the internet that if you boost 300hz you’ll achieve that, if you cut 700hz you will get that…forget about generalizing these things. Each bass guitar has a specific tone. You can’t use same settings for 4 string and 5 string bass, with different (active or passive) pickups and expect them to sound the same. It is just impossible. These numbers doesn’t mean they will be perfect for your bass guitar. They are just a placeholder and around these frequencies you should fine tune and find sweet spot for your bass.

Best EQ settings for Bass Guitar

If you are micing the amp you’ll have to think of the proper placement of that mic, room, gain, etc. Yeah, it is much easier to go directly to the mixer. Some of the older musicians would say, “Hey, just turn your bass knob up and you’ll get that bass punch”. It could work, but not with any bass guitar, not with any PA system. They just get used to vintage equipment and don’t understand the definition and clarity which new PA systems can provide you with.

First thing first, adjust your gain. Second, you don’t need anything above 5khz so you can freely cut everything above that frequency. As we mentioned before, you’ll need some big speakers to drive your bass as you would like. If your speakers can’t handle frequencies bellow 80hz, we recommend you to cut it! Boosting some frequency from 80hz to 100hz will help you to achieve bass that will knock your chest. Find it!

Punchy bass will also require cutting some of the frequencies. Maybe you’ve noticed that sometimes, on some stages or in clubs, frequency, usually from 120hz to 130hz is making such a mess with your bass, guitar, and also kick drum. It can be so annoying. You can’t cut it to the floor, don’t do that, you will lose some of vibe that your bass is producing. Find a spot where you bass will not leave a muddy, long tail note and still own its definition.

Compressing bass guitar

Compressing the bass guitar is a wonderful thing if you understand how it works and know how to do it properly.  You might have mixed acoustic guitars or electric guitars before and are familiar with how to use compression in those scenarios, but getting compression right for a bass guitar has its own challenges. The main thing about compression is making all the bass notes be heard equally. Yes, it might happen that you’ll lose some of the dynamics, but, do you need that much dynamics!? Think about it. You can be constantly at the same level in the mix, which is priceless. It can make you sound like a pro – even and consistent, even you are a beginner. Here are a couple of tips on how to set up compression on the bass.

Set the attack to moderate level, release to “fast”, ratio, for example 4:1. After that, start playing and turn up your gain knob until all your notes can be heard equally (or just turn down the threshold). If you still can’t reach that all of your tones are equal than you should play with compression ratio. Be careful, excessive compression may cause distortion, and even worse sound than natural, but it will be easy to spot it and eliminate the problem. Experiment with it a bit and see what works for you.

How to fix a muddy bass mix

You are not the only one which struggles with the muddy mix. There are a couple of tricks to prevent that muddiness which makes your instrument sound thrashy. First of all, you can cut everything below 40hz. You won’t need it, ever, especially in live performance. Basically, all of the main muddiness runs from 200hz -500hz and you should find your dirt. Also, if you play note by note, you can hear that there will be at least one note which will dominate others. It will be of great improvement to the overall mix if you cut the frequency of the tone or tones which are dominating. Somehow, that crazy tone always swims in the 120hz -130hz frequency range.

How to mix bass guitar with kick drum

Don’t let kick and bass fighting who will take the lead in the mix, let them work together. We know that you’ve probably heard this phrase like a million times and you need a concrete solution for making the bass and kick flow smoothly together. Like everything else in music, there is no specific rule on how to do this. It is up to the engineer’s choice and genre you play. If you EQ both, kick and bass similarly they are going to fight each other for the room in the mix.

Your EQing choice and level adjustment should depend on which one you’ve chosen to lead the low-end space. We recommend EQing the bass and kick opposite one another. For example, if you boost kick at 60hz – 80hz, you should pay attention and not let the bass dominate in these frequencies. If you add 700hz to the bass guitar cutting the kick at the same frequency will let bass enough room to work properly and express itself. The main point is just to make sure these two aren’t competing for space in the mix.

Using a high pass filter for a great bass mix

We think that you will be more than surprised and satisfied with your sound using an HPF (high pass filter). Some of you might find your instrument sound tinny…Again, it all depends on PA system you play on. Every mixer has HPF and it usually cuts everything below 80hz. If you could manage to cut everything below 60-70hz it would be perfect. It will cut all the sub-bass rumble that you don’t need at all. You’ll still have that mighty sub and mid definition. Keep in mind that frequencies in the range from 60hz -80hz are crucial for making the perfect low-end mix.

Main frequency ranges for bass mix

60 – 200hz:

Bass area. Boosting frequencies in this range will add depth and body, defining the low end making your bass sound rich and powerfull.

120hz – 200hz:

Problem area. We recommend you to use a parametric or graphic EQ for a precise cut of problematic frequencies.

200hz – 500hz:

Muddy area. If you notice your bass guitar need more clarity, just cut some frequencies in this range.

500hz – 1000hz:

Mids area. 500-600hz will provide you with fatness while upper frequencies will give you note definition.

2.5khz – 6 khz:

Attack area. Increasing frequencies in this range will give your bass more presence, bite and clarity.

Using a low pass filter in a bass mix

Feel free to use LPF (low pass filter) to cut everything above 5-6khz on your bass guitar channel. You really don’t need that in your mix. In that range, you only can hear things you don’t want to hear, like squeaking strings and buzz…

EQ bass from a pedal or DI box

Depending on what pedal you are going to use. Either way, stick with our lines that you read before. DI box is certainly good choice in any case. It will convert an instrument’s high-impedance, unbalanced signal to a low-impedance, balanced signal, and most important is that it will provide you with full range instrument’s frequency. Also, there will be less hum, buzz, feedbacks…sound good!?

EQ bass from a mic’d bass amp speaker

There is not such a thing that can replace a good bass amp. If you want to EQ bass with miked amp, prepare yourself for some experimenting. First, think about is your environment good enough for that job. Second, do you have a decent mic and do you know how to set it properly? If answers on these questions are “yes”, then you are ready for it. EQing bass with miked amp won’t differ than regular EQing. The main advantage with miking amp is that sometimes you don’t need to touch EQ on your mixer. Also, a cool trick is that you can mix that miked amp signal with DI signal and make your bass sound extraordinary.
