The 2B is a major upgrade from my Davey box, in terms of getting closer to HFO. Learning to use it's settings via experimentation has made its value much greater. I only wish that the audio input driven mode was more predictable, as I find it either too mild or too strong. I can't find the right settings yet, but then again, I probably need more time to figure it out. After reading various comments in the forums, I'm really looking forward to the next firmware update.
