The Gibson J-45 acoustic guitar is the prince of a range of Gibson flat-tops now referred to as "Round-Shoulder Dreadnoughts." This elegant workhorse debuted in 1942, and became an instant favorite for its rich, warm, vocal tone and excellent projection. Today, the J-45 acoustic is played by the likes of Bob Dylan, Ralph McTell, Billy Jo Armstrong, and Lucinda Williams. Carrying accurate touches such as a soft-V neck profile, teardrop tortoise pickguard, four-ply top binding, and banner headstock inlay (declaring "Only A Gibson Is Good Enough"), the J-45 True Vintage is an accurate representation of the instrument that became the standard of hard-gigging bluegrass, folk, and country artists of the 1940s and '50s.Each Limited Edition True Vintage J-45 is built in Bozeman, Montana with a top made from solid Red Spruce, a rare and highly prized tone wood, and constructed with hot hide glue, just like back in the day. This True Vintage guitar comes with a custom-made, period-correct case, and a certificate of authenticity. Additionally, upon filing your warranty registration card, Gibson will send you a specially designed jacket embroidered with the model name of the guitar they have purchased and an embroidered custom-run case cover.
