Some random thoughts on this... I think the new Strymon amp/IR pedal will really appeal to players who aren't up for the fiddly stuff with patches, mic placements in the IR and so forth that's common on Kemper, Helix and other modeler/profiler units. The Strymon reputation will probably bring in players who have been hesitant before to use any modeling. The 25 or so year old Sansamp still does pretty good, even better when used with an IR cab. I suspect a Rockman from the 80's would be the same. Overall, I think IR is the big game changer recently, especially with the price dropping into a very affordable range. Showmanship, especially in rock, almost requires a big backline of amp cabs. You may still see them at shows but they may only be there for the look. They could probably put cardboard cab props on stage and actually play through a modeler and fool 99% of the audience.
