It’s the not at all age old question – amp sim or tube amp? The truth is always, of course, that if you can’t tell the difference, then the sound shouldn’t be the thing that you choose based on, it should be other factors (price, convenience, what you need it for).
So then if you are thinking about making a purchase, I implore you to take this simple test to determine whether or not you can even hear the difference. Watch the video, listen on some headphones or good quality monitors and see if you get it right. If not, then maybe the sound difference isn’t so great that you should bag on one or the other.
