I have a 65 reissue Fender Twin, and I'm trying to create a direct profile to use with various IRs that have been converted to Kemper cabs. I've connected a Kemper DI box between the amp and the speakers as directed, and connected it to the return input of my Profiler. Every time I try to profile this amp as a "clean" amp, the Kemper detects distortion during its profiling process, and creates a distorted profile that sounds nothing like the amp.
I have taken the direct out into my computer's audio interface and can confirm that the direct signal sounds clean, so it's not a problem with the DI box. I can successfully create a clean profile by turning down the treble on the amp, but of course, this defeats the purpose of trying to capture the exact tone I want.
Can anyone provide advice for how to properly capture a clean direct profile?
