Gibson SJ Southern Jumbo ( 1942-1978 )
In 1942 the gibson Sj Southern jumbo according to the literature i've read was intended to be a promo model for the J-45 until gibson decided to include them permanently in their line of production alongside the j-45 , j-50 ,and j-55 .
The southern jumbo was made famous by country music icon Hank Williams Sr. and are known to be finer versions of the j-45 . Early models of these guitars are sought after by collectors and are expected to spike in price due to demand vs. supply over the coming years .
In 1942 the gibson sj southern jumbo was 16 1/8" round shoulder dreadnought, mahogany/back/sides/neck , thay had parallelogram inlays , bottom belly bridges , teardrop pickguard, 2 pearl dots on bridge , "only a gibson is good enough" banner on peghead , unbound 19 fret fingerboard and were made in sunburst finishes . ( few had no truss rods until 1944 )
Note : the first batch of the sj southern jumbo guitars were made with rosewood back/sides with FON # 910
In 1946 -47 they had double parallelogram inlays , no banner on peghead , & bound fingerboards , in 1948 gibson added a new modern style gibson logo ,
the following year 1949 gibson used the upper belly bridge towards the soundhole which by then was a standard feature on most of their flattop acoustic guitars .
In 1954 natural finishes were optional and were introduced as the SJN southern jumbo , a year later in 1955 one fret was added ( now 20 frets ) with a pointed style pickguard ( some still had teardrop pickguards ) .
In 1956 gibson renamed their natural versions of the SJN to Gibson Country Western with few minor changes . ( pearl crown inlays on the pegheads were added w/pearl gibson logos) .
In 1962 , due to the success of the gibson hummingbird the round shouldered body that characterized the southern jumbo was changed to a square shouldered body .
From 1962 to 1968 the southern jumbo specs went through minor changes until 1969 when the guitar was fitted with a bridge below the belly, cherry sunburst finishes were also available from 61 to 68 ( see pic courtesy of mandoweb.com ).
In 1970 to 1978 the SJ southern jumbo was renamed the Gibson SJ Deluxe Southern Jumbo non adjustable saddles in 1970 , unbound fingerboards in 1972 and 4 ply binding from 1974 to 1978 .
Round shouldered sj southern jumbos were reintroduced in 1991 in vintage finishes and hank william jr guitars were introduced in 1997 and were renamed Southern Jumbo in 1999.
