Hi,
So I do a little home recording myself just for YouTube, at least that was the idea. I'm not sure if you're asking about a specific part ie software or the whole thing so....[br][br]
I have my guitar and tube amp. The amp runs into a Focusrite DAW, which then USB's into my laptop/pc which has 2notes WallofSound. This software is free and excellent for cab simulation. Really easy to use. I use this for the sound recording.
For the video I just use my iPhone.
Then you'll need some video editing software (look for free ones at first - AVS video used to be ok). You'll need this for lining up the timing of the video with the audio which can be tricky. [br][br]
If this doesn't answer your question or you need something more specific, just let me know and I'll see if I can help further. ðŸ‘
