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 has become the cornerstone of its round-shoulder, dreadnought line. World renowned for its full, balanced expression, warm bass and excellent projection, the J-45 has been refined to carry this legacy to new heights. The Gibson J-45 Standard delivers a sound with incredible dynamic range, warm mids, and a tight punchy bass."
