“IRs that faithfully capture the tones of two cabinets used extensively by Tony Iommi”: Celestion’s first Artist Series IRs bring Tony Iommi’s early- and latter-era Black Sabbath tones to the digital sphere

Tony Iommi of Black Sabbath.

Prestigious speaker maker Celestion has announced its debut series of signature impulse responses, with heavy metal godfather Tony Iommi’s collection marking a key expansion of its digital collection.

For the uninitiated, impulse responses capture the essence of a guitar cabinet – typically mic'd up in a room – to bestow that same feel to digital amps that have no cabinet. It's a way of faking the power of a 4x12 stack for digital amp users.
