A bit off topic, but Assuming I am correct, I wonder if you'd be interested (if doing any test in future) to include a recording of kemper in the blind test with the following tweaks..
1) Definition very slightly lower. Maybe not even a full point.
2) Pick attack adjusted similarly, lowered a tiny bit.
3) Post amp block studio EQ 110hz boost from a fraction of 1 dB to maybe a bit more than 1, depending on the case, per your assessment.
Then comparing the 1) original profile 2) modified profile and 3) source tone.
I have the profile used in this comparison along the guitar DI I recorded. I reamped the DI with these edits and it did not make up for the differences. I can post a reamp later to show.
