I asked a similar question a few weeks ago too, [url="http://basschat.co.uk/topic/278725-bypassing-a-b3-in-the-fx-loop-will-it-mute-the-amp/"]the thread is here[/url].
In summary, I have run my B3 through the fx loop of my TC Electronics RH450 and it seemed happy enough. No nasty digital type distortion issues.
According to one of the responses on my thread, the pedal will not get damaged by running it in the loop, it will just distort.

I mentioned having done it and got distortion, but thinking back, I believe it was actually my Korg AX3000B that did that, and I never repeated the experiment with the B3.
