Best impulse responses 2024: the secret sauce of great recorded guitar tone

Amp modeling is rapidly taking over the world of guitar and whether we're recording at home or playing live, more and more guitarists are turning to amp and cab sims for their guitar tones. Many stock cab sims remain unconvincing, which is where the best impulse responses come in. They allow you to capture the magic of a professionally recorded guitar cabinet, load it into your modeler or DAW of choice, and take that perfect tone from your home studio to rehearsal, to the stage, and back again.

As we lie firmly in the midst of the guitar technological revolution, the impulse response (IR) has become the go-to for guitarists looking for the ultimate in simulated guitar tone. An impulse response is the reaction of any dynamic system in response to some external change, in this case, a microphone reacting to the sound of a guitar amp or cabinet speaker in a particular room.

Rather than modeling the sound of the cabinet itself, instead, an impulse response captures the character of a particular speaker, the room it’s in, and the microphone used to capture the sound. This means you can take a perfectly honed guitar tone anywhere with you, giving your sound consistency across rehearsals, the studio, and the stage.

The popularity of impulse responses is growing rapidly, but there are so many out there it really is difficult to know what’s good and what isn’t before parting with your money. Thankfully for you, we’ve done the hard work for you in picking out the best cabinet IRs available today.

Impulse responses can be a bit confusing if you’re new to them, so it’s definitely worth checking out our buying advice section if you’re buying for the first time. For those of you that already know the deal, keep scrolling for our top picks.

Best overall

The world of impulse responses is very much a burgeoning one, but York Audio is at the top of the game at the moment. The York Audio MES 212 V30 Cab Pack features 10 different mics with everything from the classic SM57 to the more esoteric Neumann FET 47. It’s also available as a $1 limited trial pack but take it from us, this is the gateway to the IR rabbit hole!

The cab itself is a Mesa 2x12 Horizontal Rectifier with two UK-manufactured 70-watt Celestion Vintage 30 speakers. It’s super versatile tonally, handling high gain and clean amps with aplomb and allowing their character to shine through with an open and lively voice. 

The MES 212 V30 it’s a great choice for first-timers thanks to the inherent versatility and unlike many other cab simulations, there’s a lot more choice in terms of microphone placement rather than just a typical ‘bright’ or ‘dark’ tone. There are also multi-mic tones in here two, with blended sounds for even more variety. You’ll need a software or hardware IR loader to use this one, but there are plenty of free impulse response loaders if you don’t have a compatible amp modeler. 

Best for beginners

Adam ‘Nolly’ Getgood is primarily known for his excellent drum sounds, but GGD Studio Cabs: Zilla Edition shows that doesn’t stop at percussion. Providing 9 different cab varieties and 7 microphones to play with, this excellent collection of IRs is the perfect entryway for those new to the world of IR, or those looking to expand their collection.

Where most IRs need a dedicated loader, GGD Zilla comes with its own dedicated plugin which makes loading and editing them an absolute breeze in your DAW of choice. Conversely, this means you'll need to export your sounds yourself to use with your hardware unit of choice. With 7 slots to customize and audition cab sounds and options to change the cab, speakers, microphone and the distance of the mic, you can dial in pretty much any sound you like.

There are loads of cab choices whether you want a 1x12, 4x12, or even something more unusual like a vertical 2x12. Each cab also has its own dedicated room sound, so you can blend in more space without diving into your reverb plugins folder. For pure ease of use and flexibility, GGD Studios: Zilla is a brilliant choice.

Best for versatility

If you’re a fan of drop-tuned guitars but find many modeled sounds to be too boomy then Ownhammer Modern Progressive Essentials will give you that heft you want without the mud. Based on the sound of British prog metal bands of the 2010s like Sikth and Tesseract, these sounds aim to give you that precision high gain tone with the flexibility for complex tapped clean passages.

We were super impressed with the sound of these and even with relatively little mixing, were able to get some properly girthy djent tones that had our heads banging immediately. Unlike some IR collections, these are very clearly labeled, which is good as there is a lot of choice on offer. With everything from the SM57 to the MD421 and a whole host of placements on the cab itself, you won’t run out of sounds for a while with this pack.

The file formats are broad enough for use on most of the major amp modelers like QC, HX, Kemper, and Axe-FX but you’ll need your own software IR loader to run these in your DAW. For lovers of all things heavy, these are definitely the IRs you’ve been looking for.

Best for rock

The mandarin-colored cab of the Orange PPC412 is a stalwart amongst stages the world over, and now you can get the sound of one anywhere with the excellent ML Sound Labs ORNG Cab Pack. Coming with seven mic sounds, five variations, plus 8 multi-mic mixes with appropriately fruity names to get you started.

Blending the best of both vintage and modern guitar tones, this highly versatile pack can chug just as well as it accommodates the wider demands of a modern rock player. The captured cab was fitted with Celestion Vintage 30 speakers and the resultant sound is amazingly full in the midrange with lovely, smooth highs that react well to a variety of picking inputs.

It comes in a variety of formats to match the demands of the majority of popular amp modelers and cab IR loaders, so you’re unlikely to come across any issues here. Handily there are also some minimum phase transform versions that play nicely with other impulse responses should you want to mix and match.

Best for metal

Jens Bogren has some serious credits to his name when it comes to modern metal. Having mixed tunes for Opeth, Between the Buried and Me, Arch Enemy, and many more you can bet he knows a thing or two about mixing heavy guitars.

If you’ve found other IRs aren’t tight when you start down-tuning past G, then the Bogren Digital Rhythm IR - Downtuned is the one for you. Whether you play a 7, 8, or even a 9-string guitar, these IRs keep your lows sounding tight, low mids mud-free, and a high end that is bright enough to cut through without being harsh.

One of the best things about these IRs is that they’ve already been EQ’d by the man himself, making it super-easy to drop them straight into your mix with minimal tweaking. You’ll need a dedicated IR loader if you’re using it in your DAW, but the formats are all there for dropping into a Quad Cortex, Helix, Kemper, Axe-FX, and many more hardware units.

Best for vintage tones

As the maker of some of the most eminent guitar cabinet speakers ever, Celestion’s foray into impulse responses makes complete sense for vintage tone seekers. The Celestion G12M Greenback IR Collection gives you that classic British tone in a bottle, allowing you to up the ante on your recordings without spending loads of money.

You get a range of microphone options including the classic SM57 and a Royer ribbon microphone, two stereo room mics for adding ambience, and even a reverse cab speaker for the open back cabinets. When you start blending these together, it really gives you that wall of sound tone from professional recordings.

Instead of messing around with mic placement and amp positioning in the room, you can simply mix the various IRs together with ease to create your desired sound. Whilst they’re not advised for modern high-gain sounds, if you’re looking for that classic rock tone these are the perfect IRs to give you that Angus Young sound.

More options...

Designed in conjunction with metal producer Kristian Kohle, the Eminence Kristian Kohle Metal IR Pack contains three captures of speakers from American speaker legends Eminence as well as some of Kritian’s hand-picked blends for some mix-ready tones.

There’s a great selection of sounds that range from hefty low end to the grittier grind, and the DV-77 speaker is particularly gnarly sounding. We loved the DV-77 Fat WAV, which just sounds great with any kind of playing whether you’re chugging low chords or tremolo picking higher up the neck.

They’re compatible with many different hardware units and there’s plenty of scope in terms of EQ to create the perfect blend by yourself. They’re more versatile than some of the others on the list, but definitely not suited to other styles outside of rock and heavy metal.

If you’re the sort of player who likes lots of choice then Zombie Cabs FN2100 Series is a good option for you. With seven microphones in four different positions and two room mics, the Zombie Cabs FN2100 Series captures that much-loved Fender 2x12 open-back cab with a Jensen C12K speaker.

Zombie Cabs goes a slightly different route from others on this list, their main appeal lies in being able to select your specific power amp. There are 16 different tube amps for you to choose from, with a selection including options from Fender, Marshall, EVH, Orange, and Vox letting you get specific with your tone of choice.

You get 30 different IRs once you’ve made your selection, as well as a bonus 30 recorded with a solid-state amp. When you add multiple formats into the equation, there are plenty of options to keep your recordings sounding fresh.

If you’re all about beatdowns and tough guy hardcore, the Ugritone Hardcore IR Pack will get you the guitar tone you need. Designed to give you tones from Minor Threat to Knocked Loose, this is a selection of sounds that mixes modern and vintage to great effect.

These aren’t your typical pure cab tones, these are sounds that are purposefully nasty to embody the typical sound of hardcore bands. Perfect for punk and thrash-inspired riffing they pairly lovely with American high-gain amplifiers, allowing for much chugging and fast power chord work.

You get five mics in total, with 7 different positions to allow you to sculpt a purposefully darker tone or pair it with something brighter for more fullness. The room sound comes courtesy of the legendary Neumann U47 and there are plenty of other options for creating a full and lively guitar tone.
