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 topsize makes it easier to put into motion it responds quicker than a bigger surface top. This makes the A-20-E 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.The installed Fishman Isys+ ffits the A-20-E perfectly. The acoustic sound will be amplified very naturally.The technical and aesthetical advanced features include bone fittings a double action trussrod voluted headstock joint cotton capped X-braces mahogany back braces high grade Derjung machine heads USA D'Addario EXP16 coated phosphor bronze strings.specsbody shape: deep auditorium OOObracing design: X scalloped with mahogany back bracesscale length: 650 mmnut width : 43 6 mmbody length: 480 mmlower bout width: 382 mmbody thickness: 92/111 mmtop material: solid A grade Sitka spruceback & side material: laminated mahoganyneck material: Indonesian mahoganyfingerboard material: Indian rosewoodfingerboard binding material: Indian rosewoodfingerboard radius: 14 bridge material: Indian rosewoodtop color: naturalbody finishing: satin open poreneck finish: satinrosette: heringbone ringtop purfling: noside binding: blackback binding: blacktrussrod: active two-waytop position dots: 7 mm + 5 mm white pearl shellside position dots: 2 mm white pearl shellfrets: 2.4*1.1 mm 18% nickel silvernut & saddle material and size: bone 43*6 mm and 72*3 mmmachine head: Derjung Deluxe chromestrings: D'Addario EXP-16bridge pins: black color white corepickguard: imported 114 tortoise Dstrap button: chromeelectronics : FIshman Isys+extra : additional genuine bone saddle and 1 x saddle underlayment
