I just love find this topic! Blogotheque have always been a really big inspo to me, to the point of creating my own channel about music through Latin America (https://www.youtube.com/@SesionesdelaCuadra) the difference is that im not a specialist in field recording or cinema, but i really try it.
When you say "guitar is either miked inside" where you put the transmisor? also inside? 😮
I really want to say thank you all for that guys! and i really appreciate the info that you shared here.
(sorry my english, i'm from Chile)
I will share two videos from the channel,
The first, just had one lav mic, the guitar line and a zoom stereo recorder
and other one where were 13 musicians in a park, two lav mics, guitar line, and a zoom stereo recorder,
i hope you like it
