I have a version 1 SD30... but also have never compare the versions. Likewise, i've not found a use for the speaker switching . I think i may actually have found a use for the modern mids, depending on where their frequencies are. All in all the version 1 is a great amp.
According to Budda, a bright switch is incorporated into the Rhythm control, and the mid controls new pull-shift function is the only thing that separates the Series II from the previous Superdrive.
