Yes it is a one-off. John had 2 JPM 7's. The Black and White which is the famous one he always used, and then there was a backup/studio guitar called the "Swiss Cammo" that he only used in the studio. I have both of them.
There is another 7 string prototype with a swirl paint job that he pointed out in the Rock Discipline video, but it's not a JPM. It was a proto that they built to develop the shape, sound, etc. for the B&W and the SC.
