It's awesome. My playing is 95%+ real cabs with no its. There have been plenty of fw updates that add something, but it seems mostly to the frfr sounds.
Imo fw 18 is a big leap for us amp/cab guys.
I did a clip, poor playing, with my real cabs should we ingredients how the guitar volume pot reacts. Used a 65 batsman, so not high gain, but does show the response.
It's in the recordings page.
