When we think of guitar impulse responses, we often think about digital snapshots of an acoustic space which can include the speaker type, cabinet type, room type, and mic type and position. These snapshots are stored digitally as WAV files so they can later be recalled and used in recordings via IR loaders or in live settings via IR-capable pedals or amps. Acoustic guitar impulse responses are very similar to standard IRs!
However, instead of a cabinet, speaker, room, etc., acoustic impulse responses are captures of specific acoustic guitars, pickups, and mics. With acoustic IRs, you can turn your DI electric or acoustic guitar into a specific (i.e., better-sounding) acoustic guitar with a specific pickup or mic configuration.
