Mixing a great guitar

Posted by Björgvin Benediktsson on 24.6.2009

Today’s guitar segment will be divided into four parts. I’m quickly going to run through the basic steps for mixing electric and acoustic guitar, pointing out good starting points in both eq and compression. Let’s start!

  1. Electric guitar
  • Compression – It depends on the instrument and how it is played if you need compression for electric guitar. Saturated rock guitars usually do not need compression because they are already compressed when distorted. But funky electrics and clean chords may need a bit of compression to even them out a bit and pull them up in the mix.
  • Equalization – You can usually filter the electric guitar quite severely if you have a nice bass track in the song. The electric guitar is a mid-frequency instrument and therefore has a lot of it’s energy in the middle of the frequency spectrum.
  • For extra oomph and body-thickness try augmenting a few dB’s around 240 Hz and for if your guitar lacks bite I would  scan through the areas around 2 – 3 KHz.

Process well and they will love you for it

  1. Acoustic guitar
  • Compression – For chord strums I usually fiddle with the threshold at around -10 with a fast to medium attack. I play with the ratio depending on the feel of the song, but it’s usually around 4:1 – 8:1. For me, I never compress the same way, and I don’t really have a method. Especially when it comes to acoustic guitar, it’s a case by case basis, so you’ll have to fiddle the knobs until it feels right.
  • Equalization – Looking over a few of my mixed songs I seem to favor the 500 Hz when it comes to equalizing the acoustic. Just a little boost seems to give mine a little more character.
  • For a lack in thickness you can sweep around 240 Hz but for more bass you can go all the way down to around 100 Hz. I like giving my acoustics a little air and shelve them a couple of dB’s up from 8 Khz. Maybe even at 12 Khz?
  • Just make sure you’re not boosting around 3 Hz if it gets in the way of the vocal. The acoustic has enough frequencies as not to have it fight the territory of the vocal. That said, you can get a little bit of the sounds of the strings and strumming at around 5 Khz.

This was supposed to be a quick post but I got a little sidetracked with researching my mixes and resources. I hope you can use some of these tips for future projects. And as always, every instrument and player is different. These setting may not work, but they are a good starting point.

Quick tips on using the knee on compressors

Posted by Björgvin Benediktsson on 23.6.2009

knee

If this is what you think I'm talking about, you should study your compressors better.

There is a lot of confusion regarding the knee setting on compressors. Low end outboard compressors usually don’t have a knee setting, but since most of you are using a DAW with built-in software compressors you will most definitely find a knee setting lingering on your compressor plug-in, just waiting for your confused fiddling.

What does the knee do?
Bluntly, it smooths out the ratio in regard to how much of an a signal gets over the threshold. It’s a relationship between the threshold and intensity of the signal.

A hard knee applies the ratio directly when the signal passes the threshold,

A soft knee applies the ratio exponentially as the signal gets closer to the threshold.

Applies compression before the threshold?
You see, if the threshold it set to -10dB and the ratio to 1:4, the signal that will surpass the threshold will gradually reach the 1:4 ratio going from 1:1 – 1:2 – 1:3 until it reaches the threshold.

A hard knee setting wouldn’t do anything until the signal reached the threshold, where it would clamp down on it immediately.

So which should I use? Soft knee or hard knee?

This varies from instrument to instrument.

Vocals can benefit from a soft knee approach, and generally drums can be put on a hard knee attack.

But feel free to experiment and see what suits your style. A soft knee on snare can be a good idea, and a hard knee on rock vocals can also be fine.

Just remember to use your ears and not follow some blogger’s advice blindly. That’s it for today, hope you can squeeze something useful from this for your audio experiments.
