Parksdesign and I were having a discussion on how the GB1 pedal looks and your looks dead on.
Is that a black d-sub and what kind of ribbon is that? I know it's different from GB2 pedal[/quote]
Looking at this reference photo you will notice that the 20 pin 3M header and ribbon cable are not used on the GB1 pedal:
The 3M header used on the GB1 pedals are much larger then the 20 pin header. It's actually a 26 pin header. You'll also notice that the 20 pin header has the 20 brass pins sticking out the back which the GB1 pedal doesn't have, just like 26 pin header.
Because the header is a 26 pin header and not a 20 pin header, the ribbon cable will also have to be a 26 pin ribbon cable and not the 20 pin cable most use:
The size of the 26 Pin ribbon cable will give you the look the GB1 trap pedal has in the reference pic above. Or it'll look like Cyland's trap since that's what it seems he used:
This 20 pin black card edge also seems to be strictly only on the GB2 pedal:
Also check out the pics from the Reference section: http://www.gbfans.com/equipment/reference/2/20/
They way the ribbon cable goes into the D-hood is hard to see in the GB1 pedal reference picture. Maybe Cyland knows how it's connected to that side of the pedal.
Kind of looks like it's just pushed in there.
