I'm addicted to the signature tone of
Vinai-T Emotive Pack IRs by LiveReady Sound. That is an ideal tone for me. What I love most about it is that it instantly gets me the tone that I want without tweaking nothing but the Amp B/M/T, and I do not find it harsh on the high frequencies. The mids are mellow, and it can cut though the mix like a Samurai blade.
I normally use it with the Axe-FX JS410 Lead Red, Orange, or Carol-AnnTucana Lead (and now incorporating the new Lead Green) but also with many other amps, from vintage Fenders to Vox.
A great thing about this pack is that it only contains four IRs, therefore you don't get options paralysis. When I bought it in 2021 I selected the first one, and still haven't even used the others.
@Deadpan would you reveal for us what cab and mike did you use there?
There are many examples of this IR at Vinai-T YouTube. He normally uses it with a Helix
