Alright, today’s question comes from my man Matthew. Matthew writes in, he says, “Hey, David. I hope you’re doing awesome. I’ve got to say, I I love everything that you’ve been posting lately.”

Thank you, Matthew.

“The question is, is it a necessity to use parallel compression on my drums, even if the drums seem to be overpowering in the mix? In all of my mixes, I make sure to use parallel compression on all of my drums, and it creates an awesome sound and gives me punch. I have never come across a situation where the compression actually makes it sound worse. I’m wondering what your thoughts are. Thanks, and let me know.”

Well, Matthew, to answer your question in short, is it a necessity? No way. Not at all. If the song isn’t calling for big drums, or the sounds that are given to you already sound big, then by all means, skip the parallel compression. It’s definitely a tool that I go to quite often. I think most mixes, I do reach for it, but in no way, shape, or form is it an absolute yes, every single time.

What I’d actually suggest is to experiment with the parallel processing, and if you are feeling like it’s too heavy, try a lower ratio. Back off the threshold. Compress less. Try messing around with the settings a little bit and see if you get something that’s a little more gentle, maybe that adds a little bit of fullness, but doesn’t overpower the track.

Just play with the compressor, but don’t forget that parallel processing can be used with more than just compression. I would try some parallel saturation, maybe some parallel EQ. Do some different things with it.

I’ve actually been experimenting myself with the UAD Culture Vulture on the back end of my parallel compression. Also, I have the Vertigo Sound VSM-3. That’s actually been winning out for me against the Culture Vulture.

But both are great. Um, Saturn. FabFilter Saturn is another one you could use. I would just try maybe turning off the compression and going to a saturated tone and blending that in in parallel, and maybe you’d get something that you’d like, and it’s not necessarily the bigger, fatter, fuller type vibe that you’re going for with saturation, but maybe it gives it some character. Gives it a little bit of some oomph, I like to say. Kind of cheesy to say that, but…

Another thought was try parallel processing your drums following that compressor with a transient designer. So, do some parallel compression, but then maybe slap a transient designer on there and pull back some sustain. Clean it up a little bit. Add some attack.

So many different options that you can do. I really love the iZotope Alloy 2 Multi-band transient designer, because I can do different things to the low end, the mids, and the top. That’s an excellent tool.

But ultimately, I just want to encourage you, man, I would actually need to take my own advice here, is to trust your gut. Listen first. Listen to what you’ve been given, and then determine whether or not you even need to do anything at all.

And that goes for more than just drums. I’m guilty of just jumping in, processing things as if I produced the track, and I’m always going and doing some sound design stuff, and you know, whether it’s…

I just picked up recently the Abbey Road King microphone plug-in, and I’ve been having a blast with that. I think I have 20 instances on the latest mix that I’m working on. A hip-hop track.

But it’s not always necessary to go crazy. So listen first, then determine your plan of attack by deciding what you want things to sound like, and then, and only then, reach for the tools to help you accomplish the sound that you hear in your head.

So, I hope that helps. Lastly, let me let you know, instead of parallel compressing the drums as a whole, maybe it’s just the kick, or just the snare that you want that extra oomph on. It’s okay to separate the process out. Many top mixers – I think Dave Pensado is the first one I saw that would just parallel compress the kick – actually, he would parallel compress the kick, parallel compress the snare, parallel compress the bass. Different elements, depending upon what the song was calling for, rather than the pretty widespread acceptance of parallel compressing the drums as a whole.

Then you’ve been following for quite a while. I heard some of your mixes, man, I know that you’ve got a great talent, so I’m going to shout out that for you, but by all means, you’ve seen me go back to a squashed parallel drum crush where I still have the option in my template to do kick on its own, snare on its own, but then the drums as a whole, but I only send the shells of the kit – the kick/snare/toms to parallel compression. I send my overheads to metal. The hat, the ride, the overheads, reverse cymbals, crashes, any miscellaneous high end sounds to a buss that I call “high end,” where I don’t parallel compress. So I leave the cymbals a little more open and a little bit more controlled, rather than smashing them with compression. I don’t want all of that extra stuff getting into the parallel compression chain.

I rambled a little bit, but I hope that helps, man. Trust your instincts. Again, Matt, I’ve heard your mixes, I know that you’re incredible. You’re a talented beast. I can’t remember, but I think you’re sixteen years old? Forgive me if I’m getting that wrong, but anyways.

I appreciate the question, I hope you appreciate the answer, and I wish you nothing but the best, my friend.

So if you are out there and you are listening, and you’d like to have your question featured in an Ask David Glenn Podcast, head on over to, where you can submit your question via the built-in audio recorder, or shoot me an e-mail to, with the subject line, “Ask David Glenn.”
