Description Product Description The Gibson J-45 Custom sits at the top of Gibson's top-selling J-45 "The Workhorse" line, first introduced in 1942. This round-shoulder, dreadnought acoustic guitar is known for its full, balanced expression, its warm bass, and its excellent projection - much of which came through subtle changes to the bracing of its forefather, the J-35. The J-45 Custom features all that rich tone, thanks to its AA-grade Sitka spruce top and Indian rosewood body. And, for unbelievable onstage tone, there's a premier active pickup system installed on the Gibson J-45 Custom.
