Okay, so I decided to create a full IR from my new cab using Logic Pro X IR utility. Almost forgot the power section of the Butterslax was also used to create the IR. The sine sweep sent through the loop return of the Butterslax into the cab captured by a blended mix of a Sennheiser E906 and a Blue enCORE 2 mic.
This is to go with not only the DI profiles I captured but also for use with any other DI profiles that I might decide to use.
I uploaded these to my BOSS TAE and played my actual amp through the TAE using these IR captures and it is spot on in response. Should work great for the Kemper as well.
