For the longest time I was never satisfied with prolonged, controlled, sustained notes in Sleep. But man, putting the EarthQuaker Devices Warden compressor, set really hot, in front of my Lone Wolf Audio Twin Snake, and then stacking the Daredevil Pedals Atomic Cock on top of that, I can hold that thing for 10 minutes [laughs]. The Atomic Cock pierces through the wall of sound for soloing and the Warden is crucial to Sleep’s never-ending sustain.

The pedal can be seen in Yvette's pedalboard, all the gear is listed in this article. This pedal was listed in the gear list of Young's 2018 She Shreds interview. She called this pedal as her "essential".

In this photo of the pedalboard of Zachary we can see a EarthQuaker Devices - The Warden

Mario Camarena uses this compression pedal almost exclusively as seen at 8:23 into the "Rig Rundown" video interview. "...I can't even imagine playing without it now - we've been using it for the past couple of years..."

She was using the Warden on her tour in 2023. I snapped a photo of her pedalboard on April 19, you can see The Warden on the bottom row.

Warden compressor is Erick’s always-on pedal, crucial for making the band’s speedy single note runs and tricky two-handed tapping licks really pop. Elsewhere, Erick steps on the Bows for a solo boost, noting that it “cuts through . . . [and] doesn’t get too muddy.”

My guitar is a Monson Nomad. Brent Monson said he had a new guitar model and I started talking to him about getting a guitar made and he showed me the mockups of it, and the specs, so we tweaked it a little bit to my taste and pickups. I wanted a big baseball [bat neck], like late 40s Gibson-style neck, and so he built me this big ass Louisville slugger-cut-in-half-slab-with-frets-on-it neck. They’re pretty heavy and tend to be denser tonewoods that take A standard and make it decipherable, and I’ve been using compressors for a long time to help do that.

Though I’ve gotta say that EarthQuaker Warden has been really a neat compressor to use. I almost don’t use it in a way, because four out of six of the knobs are on zero. I have the tone at 11 o’clock and the level and the sustain up at about 50%, and everything else is at zero, so it’s really transparent. When I turn it off and on, tonally, it does all the things that I want it to do in cleaning up my signal, but it doesn’t have any negative impact or artifacts of crushing it, though I know that’s in there and I can go nuts with it - total Nashville picker - if I wanted to, and I like that fact. But I really like it, and the reason I say that is because I really like the tone of my amps.

In this photo, you can see Bailey uses an EarthQuaker Devices The Warden Compressor on the far right of his board. This picture of his pedalboard was provided by Bailey himself on the DIIV discord.

My board for the next few tours.

In an interview with Guitar Magazine published in August 2025, Hideki "Yoda" Suematsu confirms his use of the EarthQuaker Devices The Warden compressor pedal. When The Warden pedal is active, he bypasses the Mad Professor Super Black, highlighting its role in his setup. This information is sourced from an article by 小林弘昂 on ギター・マガジンWEB｜Guitar magazine.
