No dude, then it's totally and utterly perfect. GREAT RESULT, especially when programmed. I still gotta find that spot where it almost doesn't work but still does, as you have done here.
As I wrote, on the second listen-through I wouldn't have it any other way :)
Don't change anything for the bass and guitar sounds if you ask me, you made QOTSA sound happen with humble means which is an utter achievement.
