I had similar expirience using stock profiles. I guess there's a big difference in the process of making/profiling. Also, I'm 100% that "the key" is in the cab/speaker & mic pos.
I don't have that issue with the stock profiles - they clean up well with the guitar volume control for me. For anyone having a problem with this, my guess is Distortion Sense may not be set appropriately for the guitar's pickups, so the profiles cannot clean up.
