I believe an OD should stay in the Stomp section. The input of the Profiler should not (in terms of logic blocks) be equated to an amp's input. I believe that the amp's input (logically speaking) in the Profiler is after the A/D converter, and before the Amp block.:)
If I'm understanding your statement correctly (?) there would appear to be a fundamental flaw with the KPA's input signal flow and its response and output results will never satisfy an experienced player who knows tone & recognises and is sensitive to response dynamics whilst using the internal ODs/Distortions of the KPA.
I may have read your statement incorrectly and if I have, I do apologise, please clarify for me.
'If' this indeed is the current architecture of the KPA no wonder many people aren't using the ODs/Distortion stomps because we all expect the same result from the KPA of plugging a guitar into an OD then from the OD directing into the input of the Tube amp. What should never be forgotten or overlooked is an actual stomp is designed and built to accept the output of a passive guitar into its input. The stomp's output is also designed and manufactured to feed the front input of an amplifier. Any implementation variance to this intention will never yield what is expected by today's guitarists.
I truly hope I'm wrong with the above and if not, CK should consider reviewing ASAP.
I have tried every conceivable way of altering all the ODs in the KPA over the last 3 years and I still ALWAYS yield a far better result not using them and using a regular stomp (TS808,SD1 and FD2) as you would when using a regular tube amplifier. I wish this wasn't the result as I would REALLY like to use the KPA's abilities/functions at all times.
