Sorry just saw this. The thing about the Red Llama is that it sounds different depending on the amp used. Based on that, I'd say its a very powerful overdrive which is capable of what you have described. Obviously you can use it as a clean boost with fairly minimal colour to the tone. When you start playing with the gain you can start at crunch, which increases to a driven marshally type sound. I've not spent a lot of time in the really high register of the gain so i'll check later today.
