Profiling a pedal

I noticed something yesterday and thought I would pass it on. I was profiling a pedal and started the profile by selecting a distorted sound that was close to what I thought I would wind up with. When I did this the reference sound was muddy. It was like the signal coming from the kemper to feed the amp/peddle was acting as a boost not just passing the guitar signal on to the amp. When I tried again and started with a clean sounding amp, the results were much better. The peddle sounded like it should and the profiled sounded much better.

I've got it set up just like the manual shows. Guitar into the Kemper, the direct out/send of the kemper into the pedal, then amp for the profiling signal, a mic that returns to the return/input. When I did this with the pedal the signal coming out of the kemper going into the pedal/amp was muddy and it profiled that way. At first I thought the battery in the pedal was bad. I changed it and it still sounded bad. Then I though the pedal must be bad, I had just bought it. Its a wampler and they have a good reputation. Then when I tired the pedal straight it sounded great. So I tried again hooked up ready to profile but this time I started with a clean tone on the kemper side (tab). When I say this the tone or amp coming from the Kemper, not the reference tab was clean. When I did this the pedal responded correctly. I tested it again just to be sure by starting the profile again with a distorted kemper amp cued up. Same thing, the peddle was muddy.
