I think they work great together if the TS-9 is boosting the OCD. Only problem is OCD doesn't react well to buffers in front of it. It shares that characteristic with germanium fuzz pedals.
I am a little confused, they would work well together if I placed the TS9 in front of the OCD yes? The last part of your sentence sounded like it wouldn't work.
I use my ts9 to boost OCD. Ocd gives me those 70's marshall type of drive and when I switch on the boost it delivers 80's kind of sounds. I really like them both.
