Wondering if we can maybe start compiling a list of amps/rigs that people have found to be unprofileable. Had the first huge moment of disappointment in my KPA this past week when I tried to profile a Sansamp RBI rack unit and found that it could get nowhere near close to the original box regardless of what settings I tried or hookup methods I used - the Kemper just sounded absolutely horrible next to the RBI.
What else have you guys found to just not be profileable?
