Can’t wait to see it! I agree with everything here. I usually just use my Samsung Galaxy S9 because it has a REALLY good camera and a REALLY good mic. BUT, if you want to really do professional looking/sounding stuff, it is best to not use a device that runs the cam and the mic together. If you need any help setting up Scarlett/Audio interfaces (which I am getting use to), Ed Seith and Andrew Fernandez are really awesome students to reach out to on here.
But I’m going to tell you something I tell all the students:
Wanting your videos to look clear and sound clear is great, but remember, you’re trying to be a guitarist and not a videographer. Try not to get overly wrapped up in your video presentation and spend more time focusing on your actual guitar skills. That’s the great thing about this site. NO ONE cares if you use the most crummiest quality of recording device and perfect lighting. Unless you’re trying to be a teacher online for youtube, don’t stress TOO much about what gear you have.
PS: I REALLY can’t wait to see your video! Save Me is one that very few people attempt!
