Priced at $200, the L-12 effectively filled the gap between the L-5 ($275) and L-10 ($175). Like the L-10, it had a spruce top, maple back and sides, a mahogany neck, a rosewood fingerboard and single-ply binding. Details included elaborate fingerboard and headstock inlays, a sunburst top and gold-plated hardware.
Though the L-12 was mentioned in a Gibson dealer price list dated 15th September 1932 (Joe Spann adds, “My compiled serial number list confirms that L-12’s were shipping by November of 1932”), it didn’t make a catalogue appearance until 1934 when it was pictured in the first version of catalog W. It can also be found in the second version of catalog W, which was issued the following year (though both versions of catalog W have an identical outside appearance they differ on pages 37 to 39).
Along with the L-5, L-10 and L-7, the L-12 was re-launched with Gibson’s new 17-inch ‘Advanced’ body size in 1935. In catalog X (1936) the L-12 is described as having a ‘selected northern maple rim and neck: rosewood fingerboard.’
