It is a great tool for studio, stage, and home use. It allows you to record amplifiers, play much quieter, add power section to preamps/multi effects, and do reamping.
It has a great sound, lots of options for creating a sound, an effects loop and a 50 watt power amp in 6L6 (very transparent).
I've used it for demo recordings and it's never been used outside the studio.
