Stock doesn't mean RE. So in the intial content of my Kemper 2 profiles with that names were included:
- GB - Engle Powerfall II
- TH - Engle Powerfall
If you don't have them in your unit you might look out for the particular Rig Packs with them (Guidorist, Kemper Factory Content, Kemper Merged Profiles). Not sure in which exactly but somewhere there they should be.
Just looking at the video it is pretty sure the GB one above. Sounds like Guido's style anyway
