I went for three of Tone Junkies presets: 1965 AC100, 68 Mars PA and 65 Prince. For my taste, I thought the 65 Prince was very well done and I use it a lot. I compared this new 'Tone Matched' IR with several others I have that are made for the Princeton amp and theirs sounded much better. Was it dead-on accurate to the actual amp? I wouldn't know but I liked what I heard.
