Randall's last project at Mesa was either the Mark VII or the IIC+ Reissue. He did them both. (It was probably the Mark IIC+ RI as that came out after the Mark VII).
Either way, the Mark VII is an awesome amp. It doesn't feel like a jack of all trades master of none like how some people describe the Mark V. Also the VII's IIC+ mode in particular is fantastic and its IV mode is as aggressive and modern as anything.
@Bxlxaxkxe has some killer demos of the VII.
