congrats man, very good buy!!! my buddy got one recently for his 6505+. it sounds so great!!! my new fave OD pedal!!!
compared to the TS9 that had been using, the OD9 just sounds much fuller and more open. the mid hump is there in the OD9 but it doesnt sound nasal at all, which the TS9 and my TS7 both suffer from in comparison.
one of my favorite things about the OD9 is that it retains low end better than any OD pedal ive ever messed with, the low cut is barely even noticeable. cuts just enough bass to tighten it up
