All components must be intact on power supply sent in. S&H will be free to the lower 48 states. The ASR is similar to its predecessors EPS and EPS 16 Plus. I prefer the Plus, because ASR can be a really buggy experience. They all lack resonant filters but can mimick that to a certain degree. Today getting one of these would mostly be recommended to hiphop producers. A computer with say Reason easily outperforms it.
