I use the OCD as well, sounds great through this head, the above poster is correct, this amp loves pedals and the tube buffered FX loop sounds great too! did you know you could use the fl loop as a boost? well yes you can
Anyways, I have a older Rocktron Intellifex running in the loop for some plater reverb and a wee bit of slap delay I also turn off the HUSH), sounds beautiful
This amp rocks because it loves pedals in the front and loves racks (or good pedals) in the rear effects loop...the manual has useful tips for using the loop
I have a Lee Jackson tube loop in my marshall and he has a short video clip explaining how to use his loop (which is also tube buffered - 12AX7, same as the Boogie), a lot of the information applies to the Stilettos fx loop, listen for when he says how Paul Gilbert used the loop as a boost
It's a small video of him showing how to properly use it, he used to stream it but I couldn't find a stream so this is right from his site:

Hope this helps some
I learned off it, it makes a huge difference once you learn how to properly use this kind of loop
