I wanted to do such a video for a few months : a comparison between the cab blocks of three different modelers, Helix, Axe-Fx III, Quad Cortex, in which you can freely chose your mics and position them, in front of the virtual speaker.
As I just got the Bogren Digital MLC Subzero 100 plugin, which promise something unique in its cab block ("IRDX Technology"), I added this one too. At the end of the video, as a bonus and for reference, I also show some "traditional" static IRs : my own, the ones from the John Petrucci Tonemission pack, and three different Ownhammer packs.
I recommend watching this on youtube, as there's a long description there, with chapters, my thoughts on each of these cabs, + some infos for Helix users !
