Gibson Advanced Jumbo Flattop Guitar
Description: Gibson Advanced Jumbo (AJ) flat top guitar
Available: 1935 to 1940.
Collectibility Rating: A+.
Production: About 300 total made in the 1930s.
Considered by many to be Gibson's best
16" flattop model because of its tone, clarity, power and balance in sound.
A model I really love. An upgraded version of the
Gibson Jumbo model. Please email me if you have a

The Gibson Advance Jumbo, because it was the top of the line Gibson
flat top during the 1930s, had some subtle but interesting features.
Like the neck width at the nut is 1 11/16", and not 1 3/4" like the
lesser model Gibson Jumbo. Also the neck on the Gibson Advanced Jumbo is not
as large in backshape as the Gibson Jumbo. This was by design, as the
larger neck was considered to be more or a "working class" design,
and hence the Gibson Advanced Jumbo has the slimmer and faster neck shape.
This is kind of interesting as today the larger neck size of the Gibson Jumbo
is considered "better" but most players and collectors. Has two highly
scalloped tone bars.
Another related model is the Gibson Jumbo.
A similar guitar but with less fancy trim and mahogany back and sides.
