What's an Impulse Response (IR)
- An Impulse Response (IR) is a collection of data representing sound measurements taken from a speaker cabinet or system and used by the Axe-Fx II to enable the Cabinet block to emulate a particular speaker cabinet. A test signal is played through the actual speaker, recorded, and used to generate a profile utilized by the Axe-Fx II to reproduce the measured respons. The Axe-Fx II also uses IRs for microphone simulation.
- The terms "cab" and "IR" are often mixed up.

Nearfield and farfield IRs
- Most IRs represent the tone of a speaker that was recorded with the microphone close to the speaker ("nearfield" or "close-mic'd"). "Farfield" IRs on the contrary represent the speaker sound when there's some distance between the listener and the speaker. See also Close-miked versus amp-in-the-room. There are 3 farfield IRs among the stock cabs, created by Jay Mitchell ("JM").
Matching amps and cabs
- It’s a matter of personal preference which cab model (IR) you want to combine with a specific amp model. You can choose for traditional combinations. Or be creative and innovative. The differences can be huge.
- When comparing cabs, don't judge too quickly. Each time you select a cab, you may need to adjust the amp settings to dial in a tone.
- Common combinations of amps and cabs are listed here: AMP (block): list. Forum member Shasha put together an Excel spreadsheet which shows the suggested cabinets for each amp model, based on the wiki. You can download the file here.
