And please, don't try to say that because those bands use modelers, it's because they're SMART. HAHAH. Nope. It's because of the convenience, period. Not having to hire 20 roadies extra to carry in all the cabs etc.
They are EASY to move.
They sound good(but NOT as good as a good tube amp; or else they'd have switched LONG ago haha)
They are easy to replace.
Not hard to see why many bands use them on tour. These days, any major act will try to save money any way they can. Modelers are a huge part of that savings equation.
But, I'd bet top dollar that NONE of the players have sold their tube amps.
