Martin’s The Mamas and The Papas Custom Artist Edition D-28M pays tribute to the ’60s folk group and is inspired by the vintage Martin D-28 that provided much of the rhythmic underpinning for its hits, such as “California Dreamin’” and “Monday, Monday.” It’s a 14-fret dreadnought with a top made of Carpathian spruce, back and sides of Madagascar rosewood, and a mahogany neck. Its ebony headstock faceplate features group members’ silhouettes inlaid in mother of pearl above the nut. The guitar is finished with a gloss lacquer with vintage-inspired aging toner.
