Nothing on the out. Lots of analog sauce on the way in though. Your working backwards if your trying to beef up the output, in my opinion. I have a dbx 166xl on the output of my MD/KP3 before it hits my mixer, then a Drawmer MX60 for high synths, and an Avalon U5 on the output of a Moog slim phatty for bass. This beefs up all signals before hitting a dangerous music dbox which then hits the OT inputs.
