Thanks man. As for your comment about "recorded IR tone that tells very little of what the amp sounds in person" is pretty fair to say.
I have managed to capture some great tones with a loadbox + IRs over the years, but have I managed to capture how the amp sounds in person? Nope. Shit sounds way better in person. I don't think IRs will ever be able to capture that sound/feel of speakers pushing air back n forth. I will tell you though the better sounding the amp is the better the loadbox +IR recordings will sound at least for the thrashy stuff I like to play. I've learned this the hard way lol.
I was one of those guys that saw Pete Thorn's vid on the Suhr reactive load and IRs a few years ago and was like wtf is that about? I would definitely love to be able to record with mics for sure. But being able to record a drum jam last minute at 1am on Thanksgiving night in a 2 bedroom apartment with 2 kids and a wife sleeping is awesome
