Kristian Kohle IR Pack: Rainbows and Chainsaws is a Bogren Digital impulse response collection for metal guitar, and the Kristian Kohle Black Friday deal puts it at $22.49, 50% off, until Nov 30, 2026.
It holds 28 cab IRs in total, split into two sets that pull in opposite directions.
Kristian Kohle is a songwriter, producer and mixing engineer who owns Kohlekeller Studios in Germany. His credits include Powerwolf, Aborted, Eskimo Callboy, Van Canto and Benighted.
Over two decades in the business have given him a résumé stacked with chart-leading releases, among them three Gold certifications and one Platinum.
He also runs a successful YouTube channel, where his stated mission is to teach up-and-coming engineers how to get the best tones.
The maker describes the pack as beautiful metal tones meeting grind, filth and razorblades. The 13 studio IRs are the ones aimed at modern metal.
The 15 filthy IRs are for pushing past the usual territory. Bogren Digital says they take you where you've never gone before.
Across the set you get a wide tonal palette: 14 speakers spread over 4 cabs. That range covers the gap between a dirty death metal rhythm tone and a warm vintage doom sound.
Every IR is mic'd and mixed to sit in a dense mix, so the guitars are meant to hold their place against bass, drums and vocals.
Bogren Digital says its IRs work with all software and hardware impulse response loaders. The list includes:
The maker adds that many more are supported.
The only system requirement is an impulse response loader plus any amp or simulator. The IRs handle the cab stage, so you load them after your amp sim or modeller in the signal chain.
