Yup, this amp does have an effects loop. That is where I'm running the BBE, last piece in the chain.

I should have added in my other post that I have only fiddle-fucked around with the sonic maximizer for 15 or 20 minutes with the volume way down, only because I have an old bat living next door to me, and she would most likely shit her pants if I started churning out the death metal jams at 9:00 at night.

I will be able to adjust it at stage volume over this weekend, and hopefully I will find a setting that I am happy with.
