Here is a test I made. The point is to match a rockerverb NAM capture with TONEX. Each line is first played through NAM and then TONEX. I picked the lines as based on what typically reveals differences, for example with kemper.
I find the results to be great. Tonex is nearly impossible for me to tell vs NAM.
