Big Find! I've been thinking about doing some video for the blog and decided (after a video showdown testing my Samsung Tab S tablet, my Apple iPad Air 2, and my HTC One M8 smartphone), that I'd use the phone to record the video. Since this whole thing is about the music, I figured I had to have a proper microphone recording the sound, not the "mediocre" built-in mic on the phone. After YouTube research, I found the Saramonic SmartRig interface ($30 on Amazon.) This thing works like a charm! It has phantom power if you are using a condensor mic, and also works without phantom for a dynamic mic (shown here.) It has a gain control and a headphone jack for monitoring. It runs on a 9v battery.
And I bought a tripod to hold my smartphone: (from Amazon $40) iKross 47 inch Digital Camera Tripod with 4 adapter for smartphone, tablet, DSLR camera, and carrying bag.
I'm good-to-go on the video front!
