Yeah but I’m guessing that the nature boys were special run so I didn’t know if they are representative of the Newark Street reissues.
I'm a little confused.
AFAIK the "natural" finish, sometimes called Nature Boy, has not yet been announced for or made available in the Newark Street line.
If we are talking about 70's instruments, the finish was presented as just another option from the factory.
What gets confusing is that the carved models, oak leaves and acorns, were "special" and the most common finish on a carved model was a natural finish. So some people think it is the finish that is special and not the carving. Some folks use "Nature Boy" to describe the carved models but some folks think it just means the natural finish. I can't find it but I think Guild actually used "NB" on labels which adds to the confusion.
In any event in terms of construction and what was, or wasn't hidden under the pickguard, I'm confident in saying most 70's S-100's were the same. If there were differences I would expect them and the beginning (1970) and at the end of the run.
