Quick Tip – How To Remove The Hiss From Your Pod or DI Box

This quick tip goes out to all of you who are using a Direct In Pod, PodFarm, or similar direct input box for guitar tone emulation.

If you’ve done recording with these units, you might have noticed the characteristic “hiss” that it introduces into your signal chain. We’re going to focus on removing that hiss in this quick tips tutorial.

This tutorial has been done using Logic, but it can be applied to any other recording DAW such as Reaper, ProTools, etc…

First off, we’re going to…

1. Place a high pass filter at ~70 – 80Hz

Ours is set to 80 Hz, but we’ve gone down to 70 Hz and still had good results. Adjust as needed.

We included the low pass filter in the channel EQ for ease of access later on.

After we’ve set up the high pass filter, we need to…

 

2. Place a High Cut filter at around 8.4

3. EQ Guitar Tone

Since we were going for a metal guitar tone, here’s a rough outline of the EQ that we were using.

You can see the exact EQ outlines at the bottom of the screenshot.

Why Does This Work?

When using a frequency analyzer, you may notice that there doesn’t appear to be much signal activity in this frequency region anyway. That’s because there’s no direct tone in this region, however there IS digital hiss coming from your pod unit.

Other Applications

Although we mentioned the Line6 Pod in the title of this, you could apply this technique to most guitar tone emulators out there right now if you run into this hiss problem with them. There are other times when hiss is an issue, too. You can use this approach as a start. It’s always better to fix the problem at the source, but if that isn’t an option, sometimes mixing and post-production work (read: magic) is necessary!

Things To Remember

  • Make sure you don’t cut the highs too hard, or you can start to dig into the high end tone of your guitar. Your ear is the best tool to use for this.
  • If you can, make the shelves on the low cut and high cut filters as sharp as possible. Especially with the high cut, this will help you figure out exactly where the tone drops off and where the hiss begins.
