Bogren Digital Jakob Herrmann Signature IR Pack: The Heaviest Cab in the World — Free Download

The Sound of Solid Granite

This collection delivers forty impulse responses from the Mahler 2×12, a speaker cabinet built from solid granite and weighing three hundred pounds. Its extreme density minimizes unwanted vibrations, letting each speaker’s true character come through clearly. Captured by producer Jakob Herrmann at Top Floor Studios in Gothenburg, the IRs include individual speakers with various microphones and positions, plus dual-speaker blended mixes.

Herrmann used a high-end recording chain featuring an SSL 6000G console, and applied outboard EQ from the console to some IRs for a polished, mix-ready tone. The pack also incorporates remote-controlled mic robots to find precise placements. All recordings were made in Herrmann’s own studio with his personal gear, ensuring a consistent, professional sound that stands apart from typical cabinet captures.

Mics, Blends, and EQs

Herrmann employed a wide variety of microphones—ribbons, dynamics, and condensers of all sizes—in different combinations to capture the cabinet’s versatility. The IRs are not just raw captures; some feature his outboard EQ shaping from the SSL console, tailoring the sound to sit well in a mix without extra processing. This approach gives you both clean, uncolored speaker tones and pre-EQ’d blends.

The dual-speaker mixes combine two speakers simultaneously, offering a thicker, more complex tonal foundation. These blends were carefully crafted by Herrmann and guitarist KJ Melgoza, who spent extensive time auditioning positions and combinations. The result is a set of IRs that range from focused single-speaker snapshots to rich, layered textures, all designed to work directly in your productions.

From Capture to Your Mix

These IRs are compatible with any software or hardware impulse response loader, making them easy to integrate into your guitar recording workflow. Simply load them into your favorite IR player or amp sim, and they replace the default cabinet simulation with the granite cab’s sound. Herrmann notes that speaker cabinets contribute most of a guitar’s tone, so upgrading your IRs can dramatically improve your amp sim’s realism.

The pack is ideal for reamping, as the IRs are engineered to mimic the full recording chain Herrmann uses on real sessions. You can dial in a mix-ready guitar tone directly, without additional post-processing. The blended and EQ’d IRs are particularly useful for quick, professional results, while the single-speaker captures allow for deeper tweaking if you prefer to shape the sound yourself.

Who It’s For and How to Use It

This IR pack suits guitarists and producers who want a heavy, defined cabinet sound with minimal effort. The three-hundred-pound construction and detailed capture make it a standout choice for rock and metal genres, but its versatile blends work across many styles. Use the single-speaker IRs for tight, articulate rhythm tones, or the dual-speaker mixes for lush leads and chunky chord progressions.

Herrmann has used this cab on numerous recordings, praising its loudness and versatility. The IRs are designed to deliver a polished, expensive-sounding guitar tone from your amp sim, whether you’re writing demos or final tracks. Because they’re already EQ’d and mixed, you can focus on playing and arranging instead of hunting for the right cabinet setting.
