So happy to see this. My III isn't here yet so I haven't had the chance to run through these yet. Kudos on mentioning Misha Mansoor in the IR's we worked together on, I'm sure he'll appreciate it. We did work together on those all of those mentioned packs except for Cab Pack 7 = 4x12 USA Trad 57. So if we want to be 100% correct this one isn't actually correct.
1013 --- 4x12 USA Trad 57 B1 ML --- ML Sound Lab --- Based on a Mesa Boogie 4x12 Rectifier Traditional Straight Cab with 70w V30 speakers, created in collaboration with Misha Mansoor (Periphery). Source: Cab Pack 7 - ML USA Trad 4x12
