You’re going to learn at least TWO things in this tutorial that you won’t learn elsewhere.

I was determined to make the process of learning how to EQ bass guitar more interesting. Well, now I actually look forward to EQing bass guitar because it’s so exciting!

Of course, we’re going to learn how to EQ bass guitar with a conventional parametric EQ.

I’ll even be sharing my own personal presets with you if you make it to the end!

However, the real magic happens once we start using dynamic EQ and impulse responses to take our bass tones to the NEXT LEVEL! How does that sound?

You’ll have more control than ever before and it’s not as difficult as it sounds, trust me!

You have everything you need to get started in Logic Pro X, so let’s dive right in…

Getting Started: EQing Bass Guitar in Logic Pro X

If you haven’t already checked out my tutorial on recording bass guitar, I highly recommend starting there before moving on. It has some VERY important information!

Whether you’re miking a bass amp or using a DSP-based bass amp, you should also record a separate DI Bass track with the original signal.

In other words, you should have 2 bass guitar tracks…

  • Amp/Amp Sim
  • DI Bass

If you’re using the stock bass amplifiers in Logic Pro X, you can simply record a DI Bass track, duplicate it and apply your plugin in post-production.

Why do we need 2 different bass guitar tracks though?

It’s actually become a common practice to mix these separate bass tracks together.

You can leave the DI track out if you really don’t want it. However, I’m going to be showing you how to EQ bass guitar in both ways (basic/advanced).

Before we get started though, just make sure to have done the following…

  • EQ your bass amp/amp sim so it’s not competing with the kick drum
  • If you record with a microphone, make sure you’re using bass microphone (i.e. Shure Beta 52A)

Many things can be corrected with EQ in post-production, but too much EQ can create phase issues.

We also can’t “create” frequencies that are missing out of thin air (that’s why we need a bass mic).

If you’re all set, let’s start talking about the plugins we’ll be using to EQ bass guitar…

Plugins I Use To EQ Bass Guitar in Logic Pro X

The plugins we’ll be using today are all included with Logic Pro X.

Of course, each DAW should have its own version of these plugins, but here they are…

  • Channel EQ (parametric EQ)
  • Multipressor (multiband compression)
  • Space Designer (convolution reverb)

Most tutorials will show you how to EQ bass guitar using an EQ plugin and stop there.

However, you can get WAY more control by adding a dynamic EQ (also known as multiband compression) and working with impulse responses (via convolution reverb).

I also talk about multiband compression in my tutorial on bass guitar compression, but it’s both an EQ and a compression move. That’s why it’s often referred to as dynamic EQ.

In regards to the convolution reverb, it’s not being used as a reverb in this case.

You might have heard of impulse responses (if not, READ HERE), but they’re essentially used to recreate the tone of a specific speaker cabinet.

Most amp modelling plugins can load in impulse responses, but you can always use Space Designer in post-production to shape the sound even more.

Combining different impulse responses can give you interesting results too.

Now, the order of the plugins DOES matter, but there’s no “right” or “wrong” way.

I’ll be guiding you step-by-step in the next section and you’ll notice that I’m using the plugins in the same order I’ve already listed them… EQ, dynamic EQ and convolution reverb.

I’ll also be showing you how to adapt each plugin for the Amp/Amp Sim and DI Bass tracks.

8 Steps to EQ Bass Guitar in Logic Pro X [basic]

If you want to keep things simple, we’re just going to be working with the “Amp/Amp Sim” track in this section. We’ll EQ the “DI Bass” track in the following section.

Step 1 – High-Pass Filter around 20 Hz – 60 Hz

That’s right, we may not need ALL of that low-end.

I usually set my HP filter around 40 Hz, but you might want to go up to 60 Hz if you want more of a vintage-funk bass tone. If you go below 40 Hz, you may clutter up your mix so be careful.

Step 2 – Low-Pass Filter around 5,000-10,000 Hz

You shouldn’t really hear a difference with this LP filter.

I usually set mine to 5,000 Hz for the “Amp/Amp Sim” track because I know I’ll be leaving the “DI Bass” at 10,000 Hz. I want to create a darker sound for this track.

Step 3 – Boost between 60 Hz – 150 Hz

This one’s going to depend on the tuning and the key of the song.

We’re looking for the “fundamental frequency”, so make yourself a narrow band (set the Q around 3) and sweep around this range. Once you find it, widen your Q and boost until it sounds fuller.

Step 4 – Cut between 150 Hz – 500 Hz

For this bass, I was hearing some unpleasantness around 300 Hz.

Use your ears and find a band of frequencies that adds muddiness to your bass tone and cut it. I prefer keeping the Q relatively narrow so it doesn’t start to sound “scooped”.

Step 5 – Cut between 500 Hz – 800 Hz

In this case, I cut around 700 Hz because I was hearing some “honky” tones.

Depending on your bass guitar, you may actually want to boost here so use your best judgment. I was using a pick, so that tends to make things sound more “nasally”.

Step 6 – Boost between 1,000 Hz – 2,000 Hz

We’re boosting in this range to increase the attack and clarity of the bass guitar.

It’ll be closer to 1,000 Hz, but use your ears. Just find a pleasant band of frequencies that gives your bass guitar a bit more edge and boost (keep the Q relatively narrow).

Step 7 – Insert a 2-Band Multipressor and set the 1st band to end at 100 Hz

It’ll be easier if you download the presets in the next section or you can just look at the screenshot.

Basically, we want to leave the 2nd band unaffected. We just want to compress from 0 Hz – 100 Hz to tame the sub-bass frequencies so that we can boost this band with the “make-up gain”.

That’s why this is more of an EQ move, but it would sound horrible if it wasn’t compressed.

You can go back to Step 1 and Step 3 to make adjustments if necessary.

Step 8 – Insert a Space Designer and load an impulse response

I’ll be sharing one of my favourite impulse response packs in the next section.

Normally, you’d insert the impulse response right after the amp in the signal-chain, but your track was already recorded through a speaker cabinet or the amp modelling plugin you’re using is already using an impulse response.

This one is just being used to add some colour, that’s why I’m putting it last.

If you’re going to be mixing this bass track with the “DI Bass”, you’ll definitely want to put it on a sub-mix that’s receiving both of your bass guitar tracks. It’ll glue things together so nicely!

4 Steps to EQ Bass in Logic Pro X [advanced]

In this section, we’ll be focusing on EQing the “DI Bass” track and mixing it in with the “Amp/Amp Sim” track that we worked on in the previous section.

Step 1 – High-Pass Filter around 250 Hz

It might seem counter-intuitive, but we’re not using this track for “bass”.

It’ll really clean up the low-end if we set this HP filter at 250 Hz when combined with the “Amp/Amp Sim” track. We just need the clean brightness that the “DI Bass” provides.

Step 2 – Low-Pass Filter at 10,000 Hz

Once again, there’s nothing happening in the high-end when it comes to bass guitar.

You most likely won’t even hear a difference after this move, but it keeps things clean. It’ll also focus the energy where it’s actually required.

Step 3 – Cut between 250 Hz – 800 Hz

I personally made 2 cuts in this range, but you can make as little or as many as you need.

We really don’t need that much information from the “DI Bass”. Make sure to EQ this track while listening to the other one to really hear the gaps that you’re filling.

Step 4 – Boost between 1,000 Hz – 2,000 Hz

For the “DI Bass”, it’ll be closer to 2,000 Hz.

Just use your ears and keep the Q narrow to find the area that adds more “bite” to your bass tone.

EQ Settings for Bass Guitar: Downloadable Presets

Alright, if you made it up to here you deserve a reward!

Here’s the link to download the presets we worked on today…

You’ll have the EQ settings for both the “Amp/Amp Sim” and “DI Bass” tracks.

You’ll also have the all-important dynamic EQ preset.

If you’re looking for impulse responses though, I highly recommend downloading the God’s Cab collection from Wilkinson Audio.

It’s completely free and has quite an extensive list of impulse responses.

If you’re looking for a dedicated impulse response loader, you check out Poulin LeCab2 or Pulse.

Summary: How To EQ Bass Guitar in Logic Pro X

So, are you excited to start EQing bass guitar with the tips and tricks you learned today?

If you’re not sure how to record both the “Amp/Amp Sim” and “DI Bass” track in the same performance, make sure to check out the tutorial on recording bass guitar.

Now, you’re probably curious to find out how to compress bass guitar…

That’s what we’ll be covering in THIS tutorial, so make sure to keep reading to finalize your bass mix.

In regards to bass guitar EQ though, it’s all about being precise.

Bass guitar has LOTS of overtones and that could seriously clutter up your mix if you leave it untouched.
