The goal in equalising your freshly recorded track is to highlight the good, and take out the bad. A little bass, some scooped mids, and some nice highs can give you a great heavy/rock tone.
You don't want your guitar tracks to mix into the bass tracks, and either of those to take away from the drum track. When mixing EQ at a very basic level, you need to learn about adjusting the level of Hz. Here's what I know...
The scratchy/hiss noises are usually around 5K, 8K, and 10K. Adjusting the levels down here should take away the hissing noise, but it can affect your tone as well. Here's a screen shot to give you a better idea of what I'm referring to.
In this example I've trimmed off a lot of the low end as to allow bass, and drums to come out in the mix. If you have a guitar track with that boomy heavy sound, you'll kill all your other tracks instantly. Which isn't good.
A small dip at 5K allows for some reduced hissing, and trimming off the high end sounds at about 8K and up gives my sound a better tone and cleaner distortion.
I want to mention that the screen shot above is a plug-in that's built directly into Reaper. And it's quick and easy to use.
As usual, if you have any questions about this section, just email me or leave a comment.
