Thank You -- Gibson J-45 Guitar (1942-1984) When guitar players think of gibson electric guitars automatically gibson les paul guitars come to mind , because it became a gibson trademark , just like fender strats and telecasters .
When The discontinued in late 1942 , it was replaced by the gibson j45 .
There was not much difference between the 2 guitars accept for the pickguard , fancier gibson logos in gold and minor changes to the pegheads .
Serial numbers show approximate date of manufacture.
For all dates, you will need to look at the construction technique and components used to get a more precise date of manufacture.
While physical condition can be assessed with a careful inspection, rarity and date of manufacture are not always easy to determine.
But the serial number on a Gibson can tell you when the guitar was made.
Gibson has used various methods of numbering from 1900, so it is not simply based on the serial number to identify the year of manufacture..
From 1902 to 1976, Gibson instruments have a serial number or a FON (Factory Order Number) or both.
Both guitars sound awesome ( warm & phat tone ) however , the gibson j-45 became a huge success because they were not expensive and they sounded really good ,that explains why they are still in production 'til this day.
In 1942 the gibson j-45 were dreadnought flat top guitars , made with mahogany wood (back and sides) , they had a teardrop firestripe pickguard unlike the j-35 which had a pickguard that followed the body contours, rectangular bridge , w/b/w top and back binding, 19 fret fingerboard , fancy gibson gold logo with a banner " only a gibson is good enough " ( ) ( some had no truss rods )In 1943 they replaced the pickguard with a tortoise shell celluloid teardrop pickguard , several j-45 guitars were made also in maple wood back and sides , and some had no truss rods ,in 1945 truss rods were implemented in all j-45 guitars .
My Dad said it was the same model Bob Dylan made his Blowin' in the Wind Album, though I doubt that.
