An impulse response simulates the sound of a guitar cabinet recorded with a microphone in a space. You can get them with the classics like a Shure SM57 or Sennheiser MD421 or something more exotic like a ribbon microphone, and there’s a variety of speaker combos from 1x12 right through to 4x10. Instead of taking up space in your home or studio space with cabinets and microphones, an impulse response loader pedal gives you all the tone options digitally.

They’re a great way to get consistent and high-quality sounds both for recording and playing live, without having to deal with bad room acoustics or venue-owned cabinets and microphones that have seen better days. If you don't want to carry a laptop around with you, then impulse response pedals are the way to go.

Impulse responses can be a complicated topic, so if you’re looking for more info make sure to check out our buying advice section. For those who just want to get started with the best impulse response loaders, just keep scrolling.

Our expert review:

After a long stint at the top of the guitar VST game, the makers of Amplitube dropped the much anticipated IK Multimedia Tonex Pedal to many plaudits. Combining some of the best amp models out there with a thriving community of user made presets, Tonex is a powerful way to load and create your own IRs.

You get Tonex MAX and Amplitube 5 when you purchase the pedal, opening up literally thousands of tonal possibilities for your pedalboard. The onboard cab sounds are absolutely unreal, and there’s loads of choice in terms of speaker configurations, mic placement, and room sounds.

You can tweak all of the settings onboard, but to be honest, it was a bit too long-winded for us and we found that editing through the app was a million times easier. Considering the size and flexibility of the connection options, Tonex is a no-brainer for the gigging guitarist, allowing you to take painstakingly crafted tones from the home studio to your local stage.

Our expert review:

It looks like a regular stompbox but the Two Notes Torpedo CAB is in fact a pedalboard-friendly version of their highly regarded Torpedo hardware, giving you awesome amp modeling and a preamp in a compact unit.

With its individual sections, you get power-amp and guitar cabinet modeling, as well as various room types with the ability to add EQ in post. There are 32 cabinets pre-loaded and 8 microphone types to choose from and you can load in your own IRs if you wish. Two Notes also include their free Torpedo BlendIR software for capturing your own rig.

The hardware encoders are a little fiddly to use, to be honest, and with the depth of tweaking on offer, it can get a little overwhelming doing things this way. Thankfully there’s a Torpedo Wireless Remote app available that works via Bluetooth, allowing you to wirelessly set up your cabinets to your taste. If you want to load your own IRs however, you’ll need to plug it in via the USB Micro-B socket.

Our expert review:

If you’re wanting an easy introduction to the world of IR loading, or you just need something that doesn’t cost loads of money, the TC Electronic Impulse IR Loader should do the trick. Its compact format makes it great for stacked pedalboards and there’s a surprising amount of versatility inside its small enclosure.

It comes loaded with 12 genuine Celestion IRs, so you’ll have some of the most famous speakers in the world at your fingertips. There’s an option for bass guitarists, acoustic guitars, and even a few pedalboard settings that are a blend of an amp EQ and a cabinet IR so you can run an ampless setup for live use or recording.

The best thing about the Impulse IR Loader is its simplicity. We found that changing settings via the hardware knobs and buttons were really intuitive, and its small size makes it easy to fit on your pedalboard. Plus, it has a Snake mini-game on it if you’re bored whilst your bassist messes with their settings.

Despite its moniker, the Boss IR-200 can do a whole lot more than just replicate your favorite cabinets. It’s a fully-fledged rig in a box with loads of options for guitar players who want to downsize or record at home easily. Boss has a decent history of amp modeling, and they’ve packed a lot of functionality into this pedal-sized powerhouse.

It features a hefty 154 IRs from both Boss and Celestion, as well as eight guitar amps and three bass amp models. You can also load stereo IRs, making it that much easier to run a stereo rig without having to cart around multiple amplifiers with you.

There are a lot of different settings so it will take some time to learn, but if you put in the effort you’ll be rewarded with some phenomenal tones. 128-user memory slots mean you can have lifetime’s worth of guitar rigs at your disposal, and a boatload of connectivity options ensure it will fit into even the most complex of setups.

Our expert review:

As well as being an excellent IR loader, the ENGL Cabloader features power amp sims and various microphones that make it a great all-in-one solution. Whether you want to play live going straight to the desk or use it at home into your DAW, it offers great sound an easy usability.

There are 12 pre-loaded cabinet settings, all from ENGL with 1x12, 2x12, and 4x12 options. Each one has a different variation of Celestion speakers so you’ve got plenty of options. There are ten microphones to choose from, as well as four different power amp models including EL34, EL84, 6L6, and 6V6.

It’s a comprehensive selection that will certainly suit the vast majority of guitar players and we love the ENGL Cabloader as an all-in-one solution for practice, recording, and playing live. The presence knob is also super useful for sculpting your preamp tone if you’re using it.

Our expert review:

Designed by John Suhr in conjunction with legendary amp designer Jim Kelley, the Surh Reactive Load/IR is a fantastic option for players who want a rugged cab loader and reactive load that will hold its own live or in the studio.

You can store 16 different cabinets and it comes pre-loaded with Celestion IRs designed specifically for Suhr. It was the feel that impressed us most about this unit, with the lifelike response of the built-in IRs immediately noticeable. There’s no amp sim in sight here, so this is one for guitarists who want to utilize their existing amplifier.

The toggle switches give you a 6dB signal boost or act as a high cut. The latter doesn’t cut the EQ, but rather the impedance curve making it perfect for use with amp heads. It’s not quite as full-featured as others on this list, and there’s no digital output and no cab editing software, but the rugged build quality and feel help it stand out amongst others.

Our expert review:

If you’re a lover of tube amps then the Msea CabClone IR+ is designed for you. As well as containing an excellent selection of cabinet IRs, it also features an attenuation option for taming your loud amp on stage, as well as a reactive loud for silent recording that won’t disturb the neighbors or anyone else at home.

The playing feel of these Mesa cab sims is second to none, and there’s none of that dreaded, muffled sound that plagues some IRs here. There’s a variety of options like the 2x12 with Creambacks and a 4x12 Recto cab that makes it pretty versatile, but if you do want to load your own impulse responses you can do that too.

The CabClone IR is available a little cheaper if you don’t need the attenuator, and having the reactive load is a godsend for recording your amp at home. Each cabinet has a dedicated version for live and studio use, so you can always be sure you’re sending the right signal to FOH or to your DAW.

Our expert review:

Don’t the obscure name fool you, the Sonicake IR is actually manufactured by Hotone so despite the bargain bucket price, you’re getting a quality bit of gear. It’s super simple and compact, making it a great option for first-timers and those who don’t want loads of bells and whistles.

The Sonic IR comes pre-loaded with 11 IRs, 9 for guitar and two for bass. Pretty much all sonic ground is covered from 1x8 to 4x12 and the sound quality is fantastic considering the price. There is a little more latency than some of the other loaders on this list, but it’s barely noticeable.

There’s no EQ section so you’ll be relying on the base EQ from the IRs in question, which may or may not suit your tastes. If you’re loading your own IRs, you may want to apply some low or high cuts depending on the sound before you import them.

An impulse response loader replaces your guitar cabinet, by simulating the sound of a guitar speaker. They can be software or hardware-based and are typically used with a physical preamp, amp head, or with plugins. A pedal-based impulse response loader prevents you from having to carry your guitar cabinet around with you, allowing for much easier transportation of your rig.

Most impulse response loaders come pre-loaded with sounds, so they’re typically plug-and-play pedals just like any other. However, they do differ in that you can load your own impulse responses, whether that’s one you’ve made yourself, or one you’ve purchased from elsewhere. Part of the brilliance of impulse response loaders is you can capture the sound of your rig and take it with you wherever you go.

An impulse response is a measurement of the sound of a guitar cabinet, usually through a microphone and then sometimes into a desk. When you record a guitar in the studio it goes through lots of different processes and hardware before you hear it coming out of the monitors, impulse responses allow you to capture that sound and play it anywhere.

They’re rapidly gaining popularity because it allows you to overcome the limitation of carrying amps around with you, as you can have a 1x12 or a 4x12 in your rig, and switch between them in the same song if you really want to. Just like convolution reverbs have been used for years in the recording industry, so to impulse responses for guitar are becoming a go-to for their inherent versatility.
