A guitar cab made of stone

A guitar cab like nothing else

Record your guitars with the unique sound of a 300-pound speaker cabinet.

The Heaviest Cab in the World IR Pack is a collection of impulse responses made with the Mahler 2x12 speaker cabinet. Captured by producer Jakob Herrmann at Top Floor Studios in Gothenburg, Sweden.

40 IRs from a unique 300-pound Mahler 2x12 cabinet made of solid granite
Engineered and mixed by producer Jakob Herrmann
Captured through a high-end recording chain, including an SSL 6000G console
Mic'd, EQ'd, and tailored to fit into your mix
Compatible with all software and hardware IR loaders

In Jakob Herrmann's words
What can people expect from this IR pack?

This is an extremely detailed capture of a very unique piece of equipment that I've used on countless recordings, captured with my own gear in my own studio.

The best way to describe the sound is that it's the true sound of the different speakers, because the cab has such immense density and therefore very little vibrations. The pack contains the individual speakers with different mics and positions, but also "mixed" blends of dual speakers at the same time, sometimes treated with my own outboard EQs.
Was there any other unique gear used?

I don't know about unique, but a LOT of different mics in different combinations.

Ribbons, dynamics, condenser in every size, etc. Also some outboard EQ from my SSL console was used on some of the IRs as well. And of course my remote controlled Dynamount mic robots that I used to find just the right positions.

Me and KJ Melgoza, who was my guitarist when making this pack, spent a lot of time - and our ears - to find all the right combinations.
What was your first impression when you heard the cab?

"Holy shit, that thing as is loud as it is heavy!"

Having something so unique that is also so versatile and useful when recording and reamping guitars, is really fantastic. I've never seen any piece of gear quite like it.

Even though I have a bunch of other guitar cabs, this is my far the one I use most. Also, I love the reactions from the guitar players every time I roll it up and take off the lid, because they always go "WHAT on earth is that?!"

The Heaviest Cab In The World

Did you know that at least 80% of a guitar sound comes from the speaker cabinet?

All software amps use impulse responses to emulate the cab. The fastest way to make your guitar sound better is to use the best sounding IRs available.

thank you for the share. appreciate it. I just saw the ads on youtube and got curious how a properly german engineered cab that suppose to sound heavy would sound like in IR form.
It makes no sense to say you’re not good at it. It’s like saying, “I’m not good at being a monk.” You are either living as a monk or you’re not.

I bet you cant hear any difference as long as it is miced up so what you hear in a mixroom is the same you you will hear from the IR
That is the sound coming from the cab and capture by the mic or mics.

BUT if you stand in front of the cab and play as you do live and in rehearsal room it would sound very different
We guitarists call it "amp in the room" sound

the problem is there's only 6 of these cabs around the world. How to stand in front of one ? not to mention it's probably expensive af.
