JP Prototype?
John Petrucci 4 – YouTube
Video was published in 2007 (right before the JP BFR run) but it was recorded during 2000.
I don’t see an arm-scoop, and I think the horns are somewhat pro-longed. The bridge also looks as if it’s not a JP custom bridge. Could that be a JP prototype from back in the day?
Thanks and enjoy the vid!!
