Long before fire, earlier than time, preceding death and ice, lived only a vibration.  An ancient tone sustained throughout oblivion, bound to the fate of existence…

It consumed galaxies, laid with the cosmos, and spawned countless sunn.  The universe expanded; each piece retaining notes of its primordial pulse.

The uninhabitable rock hymn, the ultimate lunar frequency, the soundtrack of creation.  Perceived by none.

Inaudible for aeons, it sat on the ears of a deaf system…  Until now.

The Aghartha Drone Distortion Preamp.

A profound relic returned from the nucleus of Earth.

Melding two legendary circuits into one monolithic drone device.

Providing 36V of internal headroom for authentic tube-like tone and response.

The Aghartha is a JFET emulation of the center input of an early 70’s first generation Sunn O))) Model T Preamp.

A singular Grimm control adjusts the wet / dry blend of a modified RAT Distortion.

Set the dial at minimum to remove the Rat from the circuit and behold the classic Sunn O))) Model T pedal platform crunch.

Or rotate the knob clockwise to blend through a wide spectrum of overdriven soundscapes, towards a vast array of textures and saturation.

Claim the archaic dissonance.

Worship the song of the eternal void.





Grimm: Controls the wet/dry blend of a boosted RAT Distortion into a Sunn O))) Model T Preamp.

  1. Zach

    The thing I admire about the Sunn O))) tone is no matter how much gain they are running, their tone is always clear and bass heavy…not a muddy mess. This achieves that and more. Stacks great with other pedals, has plenty of bass and gain on tap, and even when maxed out it still retains clarity.

  2. Ollie

    Massive drone! Killer distortion! This pedal is very useful and stacks great with other pedals weather they are from Steve, Mr. J the fuzzimp or anyone else. My bass loves it with rat at zero or fully cranked and yours will too.

  3. Ian

    Man! Ran this thru my GT 120FX loop, Holy Shit! It was an absolute monster. Put a Does It Doom Hypercoven in the mix. You can hold a note or chord for days. Next, straight into my Hovercraft Falcon 100. Pretty decent clean tone and at minimum, (Sunn T circuit) will give you a kick in the teeth. Turn that shit up! And look out! Knocked it outta the park again Steve! AKA Gandalf Of Doom! Great job!

  4. John Sell

    Instant Classic. Not only does it completely emulate the heavy SUNN drone tone, it is also the DREAM RAT DISTORTION for any doom player. The heaviness in the bass is MASSIVE and the bite and clarity past 12 o clock is like no other. It drones, it chugs, It dooms.

  5. Ilias

    It really is an amazing pedal, I even transformed a little orange Micro Dark practice amp into a drone beast. Max out the amps gain and tilt this to almost full. Easy to get into sonic trance states, exactly what I’ve been looking to achieve

    Well, hello sexy stranger.

    If you’re here in the comment section, it’s probably because you hesitate, should I buy it or not ?

    And, I’m here to tell you kindly that you can « F word » stop hesitate !

    This pedal is exactly what it’s supposed to be, a killer pedal that worth every single dollar you’re going to spend on it right now.

    The sound is massive even in low stettings, it blew me away, like.. It’s really huge. And the funny thing about it is when you think about the price of an original Model T, the price of this little gem is ridiculous compared to its quality.

    I really don’t know if I have to talk more about it, but for me, it’s definitely a home run.

    Congratz Steve for this pedal, the Aghartha might never leave my board..

  7. Al

    This thing crushes on bass. Sounds massive even out of a tiny practice amp or adds a bunch of girth out of an already dirty massive tube amp. Really good bass clarity but it shines most in the sustain department. It’s never in a rush to feedback so you can really savor those filthy droned notes. If you want to emulate the sound of distressed speakers being pushed to their limits in the studio or at low volumes, this does it.

    Absolute bottom end. It’s that fat tone I’ve been chasing. The rat blend is perfect for this. Going into spring reverb is amazing. Brings the Orange Micro Dark and Micro Terror to a new level. Your cab is gonna get a work out.

  9. Phil

    The Aghartha Drone has pretty much rendered all of my fuzz and distortion pedals obsolete. No joke! It’s actually got me rethinking my amp/cab set-up as well! Anyone on the fence about this one should really just pay up already.

  10. Dimitris (verified owner)

    Aghartha has exactly the sound I had in my mind. Absolutely heavy and devastating, worth every penny!! Massive tone, perfect rat pedal sound, tons of bass, also fantastic overdrive sound if you dial it down! Stacks really well with other pedals! Excellent work Steve!

  11. Jerred

    The Aghartha sits as a king on my pedalboard. HUGE earth-shattering tone with the knob maxed out, but it also delivers a wicked overdriven crunch that is unbeatable. It’s built very well, holds up during live gig abuse!! Steve definitely nailed it with this one!

  12. Matt

    The tone is exactly what I wanted for my foray into stoner/doom. I run it as a preamp into the return of a EHX 15 Watt Howitzer and then plug that into my 2×12 cab with Warehouse speakers. I love it!
    The one thing that is a bit of a pain is setting the internal volume pot to reach unity volume with the amp. However, that is the price you pay for having a cool one-knob design. Recommended.

    Initial reaction was WOW, massive sound right out the gate. Haven’t found the right amp to run it through to get the right tone for myself, but it does have the potential to be the foundation of my doom tone going forward! Highly recommend!

  14. PT (verified owner)

    Deeply deep and doom laden. Massively thick distortion. I almost couldn’t believe what it was doing to my tone, but after a few weeks of messing with it, I believe. Thank you.

  15. Tim B

    Sooooooo many new fuzz pedals are on the market which is great for options but hard on your cash!!!! I do have 4 similar style pedals but for an ultimate doom fuzz tone I always go with my Sabbathi one!!! This is for serious doom fuzz that takes every to another level! This gives you the tone you hear on many artist songs and helps you create so much more in riffs! It is inspiring!!!!

  16. Derek Monaco

    Two internal trim pots and one knob to churn the black dirges of hell. This pedal swallowed my soul. Stick it before a Muff and lows become girth. Stick it after a Hypercoven and become lifted into the wings of the fallen angel of death. This pedal stacks well and blows ear drums.

  17. Michiek (verified owner)

    I’ve owned, and own, a lot of (heavy) fuzz- and drive-/distortion pedals. All pedals that stay do something really really good.. and the Aghartha is staying for sure!!
    Heavy sounding pedals can have that nasty rattle/mid-high sizzle thats hard to get rid off and gets more noticeable when the decibels rise. Not with the Aghartha! Perfect in balance, super heavy low end but enough mids to have your place in the bandmix. Works great with humbucker and single coils, standard E or standard A.. this pedal can handle everything you throw at it!


  18. DB

    In the past I’ve owned a 1981DRV, an Acapulco Gold, and a Life Pedal clone. Thanks to this pedal, all three of them are gathering dust. It is so good. I was wary of a one-knob style pedal being versatile enough on its own but there’s some black sorcery inside it that makes it all work. In particular I love having the knob set at minimum for flavoring other drive pedals, but when cranked, all you need is an open chord and it’ll sound like you just cracked the Earth in half. It’s INTENSE. Love it.

    I bought The Aghartha because it is the preAmp section of the Sunn Model T amplifier. I’ve tried a few Sunn amp style preAmp pedals and this one by Does it Doom fills the roll I’ve been searching for. The Sunn Model T isn’t a super high gain amp so having that Rat circuit comes in handy for your heavy distortion/gain boost. Most Sunn pre-Amp pedals do not give you that option of a higher gain. My down-tuned guitars sound very good with the DID Pedals. I have no complaints. Also, I was stacking other distortion pedals into The Aghartha and for me, it sounds great. Was worth the purchase.

  20. Michael (verified owner)

    Wicked pedal! Sounds great, just check the videos, it will tel you more than i can ever write 🙂 But right out of the box, i was stunned by the build quality.
    Also the shopping expirience was flawless. Was a little worried to order to Czech Republic ( otherwise i would order sooner 🙂 ) But it got here in 4 days + one day on customs.
    Perfect job overall, next up is the Sabbathi.

  21. Chad Brack

    When this first released, I chose to pass it up because I didn’t think I needed a preamp pedal. After hearing people rave about it, however, I decided to grab one before they sold out. All I really need to say is “they were right.” This is rapidly becoming one of my favorite pedals; it just sounds so massive and it’s so much fun to play. When you hit a powerchord, the Aghartha commands you to hold it and ride the wave. You prepare to move to the next note, but Aghartha says “no! You shall drone.” Slides are pure joy. This thing just makes we want to play differently than I do with my other pedals, and it’s hugely inspirational. I highly recommend it.

  22. Kevin Daigrepont

    Absolutley nails the Sunn O))) Sound.
    Thundering, wall shaking low end, a nicely voiced Rat circuit, and sustain for days.
    With the knob turned all the way down, you get just the Sunn Model T, which is useful on its own or for running another pedal into it. It’s a fairly dark sounding pedal, but it’s crushing sound is perfect for low tuned guitars

  23. JamieB420

    where has this petal been all my life. I’ve been using it for about a year now and absolutely love the tone this thing puts out!! if your thinking about buying this do it now!!! you won’t be disappointed!!

  24. Jack Borders (verified owner)

    Very happy with this pedal.It stacks extremely well with my fuzzes.

  25. Chris (Narruc) Curran (verified owner)

    This is one of the five Does it Doom pedals I own. I couldn’t love a human child more than I love these pedals!!!🤘🏼🤘🏼🤘🏼

  26. Adam Parker

    I turn it up about 3/4 of the way, or slightly further. At that point, it has a heavily distorted Rat tone, with that jagged high end softened up and a LOT more bottom end. The attack is super-slow, which means the thump fills the damn room on impact. This is the 2nd Does it Doom pedal I’ve played, and the Agartha is my favorite so far, but if I run my other Does it Doom pedal (Giza) into it, the Giza adds higher and midrange frequencies like a tasty spice mixed into this pedal’s syrup.

  27. Steve T (verified owner)

    No joke, I plugged this in for the first time today, and it just put me in a trance. I was just doodling away happy as can be. The more you crank this the more the Rat comes in and the more it “fuzzes”. Amazing as usual. Heavy as a pair of elephant balls. 🤘🤘
