Thanks a lot! I totally agree with your points too.
- They are indeed seventh chords and are not spaced as optimal as they can. I am still getting used to seventh chords, as this is my second time using them, so I appreciate the feedback!
- And about the distortion, now that I focus on it, I think I found what you mean. It's definitely not clipping, so don't worry about that, as I always have a limiter on my tracks and the "distortion" also happens when I lower the gain. I am actually not sure what causes that little clicking noise... I appreciate the mention though! Maybe I'll look into it some more :)
