From Gibson:

“The J-45 is Gibson’s best-selling acoustic of all time. Nicknamed “The Workhorse” and first introduced in 1942, this iconic acoustic guitar has become the cornerstone of its round-shoulder, dreadnought line. World-renowned for its full, balanced expression, warm bass, and excellent projection, this J-45 has been refined to carry this legacy to new heights and is equipped with a red spruce top. The built-in L.R. Baggs VTC under-saddle pickup and preamp delivers the J-45’s incredible dynamic range, warm mids, and tight punchy bass, both live, and in the studio. A Gibson hardshell case is included.“
