Guitarist are the last bastion of religious fundamentalism !
But more and more do use DSP modelling now, especially for live concerts. There's nothing wrong with wanting a valve sound, but just accept its nothing magical, just a mathematical formula that just as easily can be applied digitally.

Not if you’re a guitarist :-)
