DOD FX9 digital delay

[loss1234]

I have had one of these since i was in high school and have always loved its sound
i keep hoping to find some info on this pedal, what kind of chip it used, etc but for some odd reason, there are no threads here, and no schematics online for this
box. I would love to know what type of pre and post emphasis it uses, what sort of RAM,etc.

does ANYONE have any leads?

does DOD sell schematics for their products?

thanks so much
