Wow that's weird especially coming from Matt.
So an "SV" 4x10 sounds like a "USA" 4x12 guitar cab? Do I even need to post a comparison clip?
They sound completely different.
Personally I was surprised at how well Cab Pack 11 turned out. Truth be told when I first got the idea that we needed high quality bass IRs I was extremely sceptical if it was necessary since DI bass has become the industry standard. Boy was I positively surprised. I used to do the old trick where I have two bass tracks: one of them clean and the other dirty and blend them together. I definitely don't have to nowadays and the biggest strength of Cab Pack 11 is that you don't need gain to make the bass sound huge. You can use almost a clean sound and it will fill the mix and make is sound huge. It has literally cleared all my bass mixing problems and I'm using on all the bass tracks that I mix.
Here's an example:
Listen to how full that mix sounds and how everything disappears when I stop playing the bass. In the end of that clip you'll hear the bass sound separated and you'll notice it's nothing more than bass and that IR. No drive no nothing. Just a clean bass sound and no tricks needed.
Obviously it may not be the perfect thing for all use cases and I respect Matt a lot so I'm bummed if he didn't find it useful for his use. I will soon post a music video of my band where you'll once again hear these IRs killing it. I'm using Mix 08 most of the times nowadays which is all mics on the bottom right speaker.
