If you own an iPhone with a lightning connector (like iPhone 5 and later) but don't own anything to record your playing, the Zoom iQ7 might be a nice option to document your playing. You can use it for Audio only or even for filming with the iPhone, because the microphones can be turned in a position suitable for filming.
Here's an example how it sounds. It's not exactly your good vintage Telefunken tube microphone sound via Neve preamps sound, but it's not half bad either.
No sound processing whatsoever involved. And it's around 100 US$
You need to take quite a bit more money into your hand to get to the next quality grade... and deal with a lot of cables, power supplies, boxes, mic stands etc. etc. ... not exactly the atmosphere that makes you feel 'like an artist'
Music is a big continent with different landscapes and corners. Some of them I do visit frequently, some from time to time and some I know from hearsay only ...
