A cool fab four in each tone wood, all with solid spruce tops, of course.. Pictured here with a Ford is the rosewood dreadnought-sized A1R, with a solid spruce top and premium pickup and electronics box. Yamaha also makes the slightly smaller body (AC series) in both solid back and sides (the A3 series, which come with premium gig bags) and lesser-expensive laminate back and sides (the A1 series). R stands for rosewood (yeah!) and M for mahogany. So the Yamaha AC3M would be the smaller-bodied, solid mahogany back and side guitar with a sweet pickup! And, we have it. Old Ford, new Yamaha!
