I’ve been wondering the same. While I’m sure Cliff was confident the CNFB theory and code was sound and ready for prime time. I wonder if there has been some refinements that are taking some time to get tested and out. I have been thinking that perhaps the CNFB algorithm(s) are maybe too “perfect” in a sense. I think what those that seem to be sensitive to and what they refer to as “odd distortion” (for lack of a better word) is just the effect of the difference between listening to your guitar through a guitar amp and guitar speakers standing 10 feet away vs. putting your ear 1 inch away from the speaker. That’s when you realize all the nastier sounds that get filtered through air. Even when close micing it isn’t the same because every microphone is not perfect and has a filtering effect, which in the case of the SM57 becoming a mainstay.
Also, as many have pointed out the sound settled on in a mix for electric guitar is not the tone we want to set up our sound when we’re just listening to our tone by itself. Also, I’m not trying to say what some are experiencing is their imagination.
