Still searching for an F-50 spruce/maple or a JF-65...but also saw an ad for an interesting JF-30 made in Westerly R.I.
What's the audible difference between AA Spruce and AAA?
Not trying to contradict TMG, but it's
possible a tighter grained top might sound "better" than a slightly more open-grained one, on the principle that the denser wood would have more resonance and be able to be made a little thinner while retaining strength. That's part of the theory about why red spruce is a more desirable top and bracing wood.
As TMG says, I can't ever remember seeing anything indicating Guild ever tone-tapped their flat-top wood as a standard practice , and have never seen any "specs" for top thickness .
Also, Guild's wood purchasing/ grading methods at that time have been mentioned here as being more discriminatory than the other "big guys". They bought in smaller lots directly from producers instead of bulk loads friom brokers so their grader had much more "fine control" over what was brought in and used.
Because of that it's been suggested Guild's regular and AA tops likely were as good as other's AA and AAA tops.
Grading itself, in case you weren't aware of it, is largely subjective, there're no formal standards, and the standards themselves are primarily aesthetic as TMG said. "Bear claw" for example was considered highly undesirable back in the '70s, but now is seen as possibly indicating tighter grain/denser wood and gets more respect both aesthetically and acoustically.
And did the JF-30 have the red spruce/scalloped bracing?
Guild didn't start using red spruce until Tacoma, but JF30 was discontinued before then. They did make some in Corona (between Westerly and Tacoma) before it closed.
Now as for scalloped vs standard or shaved: Depends on when built. First and second year ('87-'88) price lists show scalloped bracing but winter '97-'98 catalog shows standard, and on top of all that our guru Hans Moust has mentioned many times that even those materials were subject to error. For example that same catalog shows S100 electric as having
rosewood pickups...
Allowing for fractions of an inch variation in depth which was normal production tolerance in Westerly (where the vast majority were made) yes.
And is it a "cannon" like the 50?[/QUOTE]
According to the majority of reports, yes.
