This is a very dope and  capable Recorder! I’ve got 2 audios below. First, my thoughts, and running through some menues, with the latest 2.10 firmware which adds greater accessibility.

The second, an acoustic guitar test, mic the guitar with Rode Nt4 and the vocal with a Rode Podmic, Into the H6 Essential. I took the tracks to my DAW and did some very light mixing, EQ, Comp.
