KOENICH IR 004 | Celestion G12H-150 Redback

Experience the powerful character of the Celestion G12H-150 Redback, a high-power guitar speaker designed to handle massive guitar tones while maintaining clarity and control.

Captured in a real 4×12 guitar cabinet using three different microphones and dedicated analog microphone preamps, this IR pack offers three distinct perspectives on the same speaker.

From the focused midrange of a Shure SM57 to the character of a Sennheiser e906 and the broader tonal perspective of an Aston Spirit condenser microphone.

Designed for guitarists and producers looking for powerful guitar tones with the flexibility to choose their preferred microphone and recording chain.
