but am not sure of this is the type of your guitar, or the strings getting too old (like you mentioned somewhere in the clip as well)
This is spot on. I am about to get some new strings, I can hear them dying haha.
You also right that the syncopated style doesn't gel well on it's own. Maybe 2 guitars playing simultaneously would have been a better option.
I am happy that you agree, it sounds fuller with all the instruments! Thanks again for your feedback!
