Creamback Impossible Mix – This blend is ideal if you’re looking for a high gain, hard rock tone that’s a little brighter and punchier than the heavy mix. It produces a tone that would be impossible to reproduce with a physical setup. It blends the Creamback M in a 4×12 cabinet with a Creamback H in a closed back 1×12, using 4 mics for each (Royer R-121, Sennheiser MD421, Shure SM57, plus Neumann TLM 107 room mic), making 8 mics in total.
