Hans--
So it could be a "one off" of some kind? Thanks for your expertise!
Not to butt in, but yes we've seen examples of that particularly in '93-'94 on "DV" guitars that were spec'd for 1-11/16 but actually have 1-3/4.
I think Guild may simply periodically built batches that way simply to make the width available, or it was possible the instrument was special ordered with a 1-3/4 nut. They were
very flexible about special orders.
Because their lit always said specs were subject to change without notice, it would be easy for 'em to change a spec at will.
Normally that's seen as a means of allowing for substitution of material in case of a sudden shortage of a spec'd material used for a model.
In this case I now truly believe a running spec change like this was for the purpose mentioned above, to put some variety in the model to make 'em more accessible to a broader customer base.
Don't like skinny nuts? Check again in 6 months, see what I mean?
Another potential is there were a couple of very short-lived models listed in the '96 catalog, A25 and A50, that were spec'd with 1-3/4 nuts, and that means that they had tooling for it as a standard width at the time.
I can see then that it's also possible that they used unused necks from those on later F30s, since Guild was also known for being loath to waste perfectly good parts.
Hans likes to keep things simple and is short of time, I suspect that may be why he simply confirmed that something very close to 1-3/4 was definitely possible at the time.
I'm just trying to help out with observations that could explain how it could happen.
I'm actually starting to dig the fact that there is so much potential individual variation even between same year models.
PS something else just occurs to me, that Hans has repeatedly mentioned that marketing materials contained errors and thus it's possible that the most commonly listed 1-11/16" spec is actually incorrect sometimes!
