New from NAMM. I saw it in the latest Acoustic Guitar magazine. The back is walnut instead of mahogany. From Guitar World magazine...... NAMM 2019: In addition to Gibson’s recently unveiled Classics and Contemporary electric guitars, the company has introduced a new series of acoustics, dubbed the Generation line. Aimed at younger and entry-level players, the affordable line boasts high-quality, USA-made guitars “built by the same hands that make the J-200 and J-45’s,” according to Gibson There’s not much video out yet. I think this could be a winner. I’m a Martin guy but the J-45 sure is a song writer’s guitar.
