I acquired this set in March 2009 and it has a market value of $290 in it's current condition. It is an original Silvertone 1448 guitar with amp-in-case. This guitar has a 2-bolt neck attachment, which seems to indicate it is an early 1962 production model. The fretboard is approximately 15.75 inches long and has 18 frets. The guitar is complete, with the exception of a small screw missing from the pickguard and the rosewood bridge. The amp shows chassis number 185-10010 and appears to contain the original tubes. The Outer Case has been poorly repaired, with old tape on two corners and some small nails on one of those corners. One hinge has been replaced with a piece of leather screwed into the body. There are signs of corrosion on the Metal Parts of the case and one plastic foot is missing from the case.
The 1448 is considered by some to be the guitar of guitars. It has a single lipstick tube pickup with masonite/pine body and a swoopy headstock with vinyl sidewalls a metal nut, adjustable bridge, and the amplifier built into sturdy case. The 1448 is the one; the guitar that pretty much sums up the entire Dano/Silvertone philosophy in one package. It's the guitar you certainly see the most of and that's because Sears sold a boatload of them from 1962 until 1966 or so, when they were replaced by the 1451.
This package first appeared in the Sears catalog in the Fall/Winter 1962 edition. The following is straight from the catalog description: Electric Guitar and case with built-in amplifier. Imagine all this plus a 45-rpm how-to-play record at one low price. You get a fine quality single pickup guitar with tone and volume controls. Brazillian rosewood fingerboard. Solid center body. Handsome simulated leather covered hardboard case with its own built-in amplifier and big 5 inch speaker. 2 tubes plus rectifier for good tone plus plenty of volume. $67.95 cash!!!!
It is the preferred guitar of Dexter Romweber, Cat Power and Beck, and the secret weapon for guitarists the world over. Ladies and gentlemen, the elegant awesomeness of the Silvertone 1448. A true master stroke of genius from Nathan Daniel and Joe Fisher.
