I know I’m asking for a unicorn. The shooting situation prohibits lavs or stick mics on stands, so it has to be a shotgun.
I know and use real, professional shotgun mics in my day job but can’t apply those to this after-hours “hobby” stuff we’re shooting. Also, I’m lending gear out to amateurs so even if a “proper” shotgun was in my budget, I probably wouldn’t be loaning that out to these folks.
So, given the parameters of the shoot, I need an affordable low-end solution that can help pick out the vocals above the instrument. Isolating the vocals in post is a lot of work and generally unproductive.
Appreciate any specific suggestions.
