With the effects loop, there is a huge volume drop and its not worth the effort needed to make it sound alright. Just run all effects in front of the amp. If you really need something in the effects loop buy the actual pedal and run it in the effects loop.
I just picked up a boss-gt10 for $200 canadian. Very happy with the quality and build of the product and they work great on orange amps. mine going into a TH30. Im very happy with my set up now
