Don Buchla originally conceived the Buchla Thunder in 1989, looking like something out of a science fiction movie the design is still something to behold after all these years. Ergonomically the Thunder seems to make complete sense too. Diagonal strips give you continuous control, with guides that match a resting hand position and put controls where your hands would go.
The Sensel have worked closely with Buchla designer Joel Davel to ensure an authentic recreation of the Thunder.
If you already have a Sensel then the overlay will cost you just $59 and to buy a full sensel system then that will cost you $269.
