rather than going to the Cab List, you can also just turn the Value knob on the cab number to cycle through cabs. just mentioning you don't HAVE to go to the list to change cabs.
however, once in that Cab List, you can also hit the FILTER button under the screen to Filter cab sizes like 2x10, 4x12, etc.
when adding cables to your blocks, the Enter key works like it did on the II, but there is also a dedicated CABLE button under the screen as well.
be sure to check out those dials and buttons under the screen, as it changes depending on what screen you're using.
also always remember the mantra: Store, Enter, Enter.
i think you overwrote scene 2 near the end of the video only because the names were all J, K, F, etc. for the quick demo. if you had a more proper preset name typed out, that would have been more obvious.
great video! thanks for recording that. it's nice to see people's first impressions of gear, and how they learn it.
