Richwood Master Series are all handmade acoustic guitars made of premium selected tonewoods professionally set-up before packing.Our Auditorium model is elegantly shaped yet the body is deeper and thus delivers a warmer tone that suits not only the fingerstyle player but also the flatpicker perfectly. The smaller surface size of the top makes it easier to put into motion it responds quicker than a bigger surface top. This makes the A-20 perfect for fingerstyle playing. The solid sitka spruce top combined with mahogany back and sides result in a light yet warm and lively tone. The 20 series has a satin finish which gives it a more natural look.
