Hi dazzer. Ian had been using a number of different prototypes in the last 12 months but many of his best sessions were done on the proto that is exactly the same as the new production iSonic 50. He was very excited about that particular board and made sure sure its shape was translated exactly into the production board. I think one of the first of these was his session on the Easterly on Thursday, February 23, 2006 abd there were a few in June or July where he is already calling it the Isonic 50 proto.
I have just had my first sessions today on the production board and it definitly works for me!
