Description Product Description The Gibson Acoustic J-45 Custom Mystic Rosewood is a classic-styled acoustic-electric guitar with gorgeous "mystic" rosewood back and sides. This round-shoulder, dreadnought acoustic guitar is known for its full, balanced expression, warm bass, and excellent projection - which was developed by making subtle changes to the bracing of its forefather, the J-35. Well, thanks to its sitka spruce top and rosewood body, the J-45 features all that rich tone - and then some! On top of that, you get an active pickup system installed on the Gibson Acoustic J-45 Custom Mystic Rosewood for unbelievable onstage tone!
