Guitar emulator for ardour

So previously I was using heavier 7 strings, here a demo I did on FLstudio, but now that I switched to linux I wonder if there is something similar

The first thing that pops in my mind is Guitarix.
They also list some alternatives on their website (bottom).

EDIT: or you could run heavier7strings in Wine ?
