Since low end can handle lots of processing, we are able to use heavy compression, multiple layers, different ampsims for some grit, even Melodyne (trust me on this) to create a fantastic bass tone and make others wonder how you get that kind of bass sound.
I use this kind of technique mostly on Modern mixes rather than old-school songs. This isn’t the only way to mix bass. It’s 1 way to mix bass and my preferred one.
Also, feel free to check out my whole Full Signal Chains For Each Instrument Series.
Let’s get started!
Let’s get started!
Source… Source… Source…Since this is a mixing tutorial I am assuming that you’ve recorded a decent bass sound, but if not, let me share a couple of quick tips before diving into the really heavy processing tips.
The Bass DI (Direct Input signal) is the signal that you get right away from the bass guitar itself, Bass Guitar -> Audio Interface. No amps, No pedals, No cabinets.
Try to get a nice clean and balanced sound out of your Bass Di. Avoid a muddy sound by buying new fresh strings or, if money is an issue, use a MIDI program that can play bass.
It is not a shame to use software, especially for your bass tone, which is one of the hardest things to get a great source sound from, if money is an issue.
If you are trying to get something mediocre to really good then your bass guitar with some new strings and being intonated will work just fine.
But if you really want to surpass your average bass tone and get superb bass tones similar to famous record labels you ‘ll need to improve your Source/DI tone, no matter if it’s a real bass guitar or a MIDI one.
You’ ll need to invest $300 minimum to get a bass guitar that will give you a professional DI sound.
That’s why a bass VSTi (Virtual Studio Technology instrument) can really save you tons of money plus give you fantastic DI sounds with lots of bass guitars to choose from.
Here’s a couple of some of my favourite bass programs that I’ve used in many of my productions:
- Spectrasonics Trilian – Bass Module Software (my No1 Choice so far)
- EWQL – Hardcore Bass
- Prominy SR5 Rock Bass
Recording: DI Signal, Amp or Pedal?Truth is that you will use all of the 3 channels but if I highly suggest to record DIRECTLY to your Audio Interface. Why is that so crucial?
The DI signal (Direct Input) is the “mother” of the signals, the cleanest, most balanced signal and the best to play with: You can easily re-amp the signal, using software and get all the harmonic distortion you need in no time.
But, what happens if you want to record the bass amp using a mic and ditch the DI signal completely?
The Importance of the DI SignalLet’s say that you want to record your amp using a mic. You’ve set up your mics, recorded everything and now it’s time to mix!
The low end of the amp/pedal will make your life hard. Period.
The bass frequencies that your amp/pedal produced are not mix friendly. While the sound rocks in your room, it would be hell to mix your bass guitar and co-operate with the rest of the mix.
The DI signal has the cleanest, most powerful and mix-friendly low end. The low end that your amp produces creates more drawbacks than benefits.
That’s why we will use the low end of the DI signal along with the grit of an amp using multiple tracks/layers and EQ.
I Don’t Want To Use A Digital Amp But A Real Amp… What To DoIt’s really simple. You can record your amp/pedal signal AND your DI signal simultaneously.
You just need one of these: Radial JDI.
How To Use JDI With Electric Bass
It’s a pedal that can help you record the signal of your favorite amp along with the DI signal.
The process is really simple:
- It splits the signal into 2 signals.
- You create 2 tracks in your DAW. For example: DI bass, Amp Bass.
- Send each signal to its corresponding track.
- Ready to record – 2 birds with 1 stone!
Layering: Using Multiple TracksThe bass guitar is a tricky instrument to play with and it takes lots of process to make it sit in the mix.
That’s why I love to separate it to at least 2 tracks. The DI track and the amp/grit/distortion track.
- DI Track: This tracks plays the role of the low end of the mix. I remove all the mid-high frequencies and keep just the low ones using a low pass filter. (More details below.)
- Grit Track: This is the track that keeps the mid-highs of your bass tone. I use an bass amp or a pedal (digital or analog doesn’t matter as long as it sounds good) to get all the harmonic distortion I want. I remove everything under 250Hz, but we’ll talk about mixing later in this guide.
It’s… Mixing Time!I know I know, that’s the part with the most fun and it took too long to talk about, but trust me without the above information it wouldn’t be fun… at all.
Let’s get started!
- Split your bass signal into 2 tracks. Name one track “Bass Low” and the other “Bass Grit”, you get the idea.
- Send these tracks to a group track. Name it “Bass Group” or just “Bass”.
- Use a filter and remove the mid-highs on your “Bass Low” track. Keep only the lows up to 250Hz or so, use your ears.
- Use an amp, amp sim, pedal or pedal simulator to your grit track and generate harmonics with grit/distortion.
- Use high and low filters to remove all the frequencies to your grit track, except the 250Hz to 5Khz (or less) region.
Just play with the volume of these 2 tracks and stop wherever it sounds right to you.
It really helps to play with these faders along with the drums and try to gel the kick with the bass guitar.
Mixing Time… Part 2! – Processing The Bass GroupNow that we’ve created the basic tone of our bass, it’s time to really go to town with our bass group.
We will not use any other plugins on the separate channels, cause these 2 channels actually form one instrument so we’ll have to treat it as one instrument too.
So use your plugins to your Bass Group.
Use a high pass filter and remove some low end around 50Hz – 60Hz. I know what you’re thinking, removing bass from bass?? Trust me these frequencies are so low that do not serve anything useful, it’s just low end mud. Plus, with all the processing that we’ll do now the lows will creep back up to us.
Use a limiter gently to remove some really aggressive peaks. The compressors that we’ll use next will work easier and in a more effective way by doing so.
Use a Waves 1176 compressor or if you don’t own one, just use a FET compressor of your liking.
If you can’t afford the 1176 model from Waves just download for Free the 1176 model from Antress. It really rocks and it’s free.
Settings: Aim for heavy reduction from –5GR to -10GR, 4:1 or 8:1 Ratio, quick Attack around 3 to 10ms and Fast Release.
Now use an another compressor. Still have some sudden peaks? Use a hard compressor. Need some gentle compression to even out the dynamics? Use something more gentle like the Waves CLA2a.
If you can’t afford it, here’s a free LA2A clone for you by the Antress team.
Mixing Bass Guitar – Time For Some EQRemove some mud by cutting some db in the 250 to 500Hz area with a wide Q.
Cut around 50Hz to 80Hz so your kick drum can cut through.
Remove some low end mud by cutting around 150Hz to 250Hz.
Now aim to reduce the “cardbox” sound. Cut some db with a wide Q to the 500Hz – 1.000Hz region.
Feel free to add a new band and search the frequency spectrum for more abnormalities and cut them or even boost frequencies that sound good.
Give Me More… Tightness!You really think that after all this heavy compression your bass frequencies are tight enough, right?
No they are not and frequencies under 250Hz need to “sit in the pocket” giving us the freedom to add all the instruments we need in a busy metal/rock/hip-hop or even an epic-metal production.
For this exact reason, our last step (I promise IT IS the last step) we’ll use a couple more plugins.
Multiband CompressionThe best way to make sure that our low end acts like a “good boy” and doesn’t interfere too much with our dynamics is to add a Multi-band Compressor.
I love using the C4 Multiband Compression by Waves but you can use this Free multiband compressor too.
We’ll use 2 bands:
- Band 1: The first band will aim at the 0Hz to ~80hz region. That is to make sure that our sub lows are absolutely tight.
- Band 2: The second band will aim at the ~80Hz up to 250Hz region.
With all this Gain Reduction you’ll feel (and hear) that your bands are noticeably tighter but also lower in volume.
Make up for it by using the Make-Up Gain of your multiband compressor, bypass the plugin, listen to the before/after effect and match the volume.
Our Final LimiterNow that you are finished with your multiband compressor, add a final L1 Limiter or just Download the fantastic and free Gclip Limiter.
Do not exceed more than -3 to -4db here. But if you do, chances are that you haven’t compressed enough to your compressors that you’ve added earlier in your chain.
So please go back, compress more and then come back to your Limiter.
Some Really Cool Tricks For A Professional SoundIn this chapter I’ll give you 3 more tips that will make your bass tone shine and these are some of favourites on how to mix a bass guitar.
These are the tips I use daily and I really can’t live without them from the day that I’ve given them a try.
They saved me lots of hours editing, made my life easier and they’ll make yours too.
MelodyneYes, you got that right. Melodyne!
Melodyne is mainly used for vocals but you won’t believe what it can do to your bass.
Let’s say that a client sent you to mix his song, but he recorded his bass without even tuning it properly. You won’t be able to get a decent low end with that kind of bass tone.
And since bass is mostly a monophonic instrument Melodyne can do wonders on it.
You just open Melodyne, lock the notes by double clicking them and you have a perfectly in-tune bass, how’s that sound?
Waves Bass RiderSince bass needs lots of compression, we sacrifice some of its life and punch due to it.
Wouldn’t be perfect if we could automate the volume of each note just by using our volume fader? This way, the signal that we would feed to the compressors would be already “manually compressed” since the volume would be evened out by our own hands.
This would result in less errant peaks, thus making the compressors give us what we want with less moves.
Well, we could automate the volume by hand, but this would take days or even weeks to complete… But there’s a solution and it’s called Waves Bass Rider.
This thing draws automation curves all by itself.
It saves you an enormous amount of time plus helping you focus on other stuff (like composing music heh!) instead of drawing Automation curves by hand.
I highly suggest you to give it a go, you’ll love it!
Chorus or ReverbChorus on the bass alone will destroy it. No chorus-reverb is good on the low frequencies.
For this reason you can can create an Aux Track and add a chorus there. Then send your bass via your fx return.
Then add an EQ and remove all the low frequencies. You’ll end up with a wider bass, but don’t overdo it though.
To sum up: Just use chorus on the mids and highs of your bass.
Monitoring The Signal ChainAs you can see, the bass guitar is really the No1 instrument that you can really go to town and still accept all of your crazy tweaks.
Since you’ll use lots of compression don’t be afraid to go back to your signal chain and be more drastic.
Let me explain…
For example, if you’d started with a cut of -7db at 70Hz and then have added a compressor, you might need to go back and cut 4db more resulting in a -11db cut.
It wasn’t your fault, your judgement for a -7db cut was great, it’s just that the compressor that you’ve added after the EQ emphasized your previous cuts and worked against you, so go back and be more drastic on your EQ.
Same things applies to the compressors. If your 2nd compressor works too hard you might need to go back to your 1st one, make it compress harder and then adjust your 2nd one.
It’s everything about balance.
ConclusionYeap that’s over 2.000 words, but I really wanted to cover anything – okay almost anything – about bass and help you improve your bass tones.
Thank you for following me on this post, I know it seems “too much” at first, but it’s really nothing if you experiment a couple of times and keep the things that improved your tone.
I guess it’s time for me to take a break and listen to some Deftones!
If you’d like to “thank” me for this post, I would really appreciate it if you could give it a like, follow, google plus it, you know all the good social media stuff!
