It might have been Frank's first Super Pas prototype that he threw in the garage 32 years ago. One off. Just kidding of course.

From what I understand the very early Super Pas, the mod was done right on the original Dyna circuit board, no new selector switch, or new jackset. But the Noble switches should have been there. (all the early Super Pas I've seen had them).
The hand written label with Sharpie, only Frank can verify that.
I am just considering myself lucky for getting that SuperPas 3 with one regulated power supply, listening to it right now with Mark Knopfler playing. Great sounding, one off Super Pas 3.
