I have the OmniCabSim Plus pedal and yup, it's as terrific as everyone in this forum praises it to be. EQ / direct box / cabinet simulator / headphone amp. It sounds tremendous and is the ideal tool to include at the end of your effects chain.
The only knock I have is that the pedal continues to "evolve" -- it's steady being tweaked and modified. I only wish I had some of these newer tweaks on mine!
