We''ve renamed the existing Basestation the Basestation Pro. What was previously called the Tau Basestation is now called the Basestation and will be the standard basestation that ships with an Alpha or Tau shortly (although all current Alpha orders will ship with the existing Basestation Pro). The current Basestation Pro will become an optional extra for an Alpha or Tau. The main reason for this is that we can only ship the Basetation Pro to a limited number of territories, the ones in which we have gone through the (usually substantial) pain of gaining the correct electrical safety approvals. Gaining these approvals has proved to be expensive, time consuming and difficult. The new, simpler Basestation comes with a 'Wall Wart' style mains adapter that is already approved for a large number of territories, including some that we cannot currently ship to such as Australia. The Basestation Pro will continue to be available for European and probably US customers (although, astonishingly, the US regime requires a quarterly factory inspection at considerable expense and hassle - what for is anyones guess - so we may have to omit this territory). We may in time introduce an intermediate model that features the Basestattion Pro's pedals, MIDI and extension functions but is also Wall Wart powered.
I hope this clarifies things - we've only decided to do this in the last couple of weeks and website copy is still lagging a little behind, apologies for that.
