Impulse Response Pack 1: Ultimate Heavy Cabs
£39.99
Premium, Mix-Ready Impulse Responses for Professional Heavy Guitar Tones
When crafting the perfect guitar tone, every detail matters, from your guitar and pickups to the amp and pedals. But there’s one critical element which is often overlooked: The guitar cabinet. In fact, some argue that the choice of cabinet impacts tone even more than the amp itself.
That’s why we created Impulse Response Pack 1: Ultimate Heavy Cabs. This premium IR collection delivers ultra-authentic cabinet simulations for mix-ready tones in any rock or metal setting, elevating your guitar sound to professional standards.

As well as the raw Impulse Responses, we have added a folder of professionally EQ’d IRs for clarity, depth, and seamless integration into any mix – whether in the studio or on stage.

“I’ve waited 20 years to stop needing to mic up real guitar cabinets. That moment has finally arrived. These are the best quality models I’ve ever used for heavy guitar sounds and make getting world-class tones way easier than it should be.”
What Are Impulse Responses (IRs)?
An electric guitar tone consists of 3 main things: The guitar, the amplifier and the speaker cabinet. Impulse Responses (IRs) are digital files that capture the sonic characteristics of real-world spaces, microphones and, in this case, guitar cabinets. These files allow you to replicate the tonal qualities of any cabinet setup, without the need for a physical cab and microphone(s).
To use an IR, you simply load the file into an IR loader. This is a software or hardware tool designed to process and load these files into your signal chain. Most modern amp simulators, digital audio workstations (DAWs), and effects processors support IR loaders. Once loaded, the IR will interact with your guitar tone, giving you a mix-ready cabinet sound, as if you were micing up a real cab.
In this pack, we’ve meticulously captured the most authentic, real-world cabinet sounds, using high-end microphones and carefully selected speakers, allowing you to seamlessly integrate these tones into your workflow. Whether you’re recording in the studio or performing live, this collection offers you the flexibility to achieve exceptional guitar tones without the hassle of setting up an actual cab.
