Impulse Response Pack 01 is not a random collection of hundreds of nearly identical files. It is a systematically captured library of 76 impulse responses from real guitar cabinets.
Different combinations of cabinet, power amp, speaker and microphone position were measured, allowing you to compare not only different cabinets, but also how the complete signal chain influences your guitar tone.
The collection includes captures from:

Marshall 1960A 4×12
Laney Ironheart 2×12
Laney Lionheart 1×12
Harley Benton 2×12 V30
Eminence Legend v12

Different real power amps, several Shure SM57 microphone positions and individual speaker measurements from the Marshall 1960A are included as well.

76 files with a purpose
The focus of this collection is on meaningful, repeatable tone comparisons.
How does the same cabinet react to a different power amp?
How different do individual speakers inside the same 4×12 actually sound?
What happens when the microphone position changes?
Impulse Response Pack 01 was created to let you explore exactly these differences.
