My dad got to play a prototype Parker Fly while doing some collab at the Fishman R&D facility. (I’m not sure many generations, but fishman made the piezo bridge pickup for the more acoustic sound.) Of course this was well before phone cameras but the way he described it with the naturally curved ergonomic neck and stuff made it sound like pure magic. Gotta say, when there was one I could play at my local music shop a couple years later, it didn’t disappoint. Too delicate feeling for me but it felt like the future.
