This is an impulse response pack made for guitar.

It has two different sample rate options, 44.1kHz and 96.0kHz. The pack includes 20 files per sample rate (40 files in total), which correspond to these configurations: 1 dynamic microphone at 0 and 45 degrees from the horizontal axis and 1 condenser microphone at 0 and 45 degrees from the horizontal axis.

Each configuration has five different files, which correspond to the position from the speaker. These positions are shown in the image bellow.
