Here is a list of the best free guitar cab IRs or guitar cabinet impulse responses.
Just in case some of you are unsure of what these are, here’s a short explanation.
An impulse response, or an IR, is an audio file containing a recording of a short audio signal being played through a certain piece of equipment or in a certain space. Take a listen to an impulse response file and you’ll discover that it sounds like a short burst or a pop. But, load that same file in an impulse response loader and you will hear a faithful sonic recreation of the space in which the IR was recorded. Or, in the case of a guitar cabinet impulse response, you will hear the frequency response of the sampled amplifier. The process which makes this possible is called convolution. It allows us to save a certain frequency response as an audio file and then apply it to other sounds.
