Hey @anarchrysalis nice use of the loop pedal!
I mentioned that I'd swing by and suggest some ways of improving the sound production for you and I guess it really depends on which way you record video.
If it's on an iphone, you might benefit from the itrack Pocket like I've got - you can plug your jack straight in and there is some basic amp modelling (though unlikely to be anyone's 'go-to' sound) but I think this would be the easiest option.
Alternatively if you're using either an iPhone, android phone or a computer to record, you might find a simple 2 input mixer useful. You could point one mic at your amp and second one at your face - if you point the amp away from the direction of the vocal mic you should get a clean vocal. You can then use an app or video software that will allow you to add the 'room' in later with reverb. Either a USB model or, if you've already got a mixer like that, an audio cable that runs into USB - your device should allow this as the audio input source.
Alternatively, as a no-cost option, you could turn down the amp, move it closer to your recording device & drop the vocal mic. That way you're eliminating as much noise amplification as possible.
I think either of these ways would be beneficial but obviously dependent on budget & time. Sorry for the long comment but I hope that you find it useful.
No need to apologize for a thoughtful, comprehensive response @elliotjgardner! I appreciate it greatly and will look into it. I've been looking at a good all-purpose mic that a friend who runs a studio recommended.
And what did you use for video?
