just an Update on the live usage of the plugin: worked like a charm and had a good response from friends.
My setup was just the DWARF with the plugin and the mx5 for the fx/ir. Midi switching via ableton. I missed to setup my cam for an audio sample in the room but maybe next time.
Venue was a small room for 60 people - which was packed. Our Sound engineer was glad he only had to dial in one JCM 800. My setup was just straight into the mixer and out to the PA + I got a little more space on stage.
On thing I would do differently the next time is to have a small amp+cab for onstage sound. Notice the sound in the first row was a little lacking.
