Happy Saturday! So I've been playing with this over the week, and I even took a crash course on chord structure. I went over it with a really fine toothed comb and fixed pretty much everything that was bothering me. There's a couple of spots where I couldn't quite hear what was going on in the original, but they're at least mostly "musically correct" now.
I came up with a better grunge guitar patch by feeding a couple of sine waves through the built-in amplifier on the Jupiter-8. First time I actually found sine waves useful. I also used some of my experience messing around with equalization.
Anyway I hope you like it, I definitely learned a lot :)
