The Songwriter Series is developed to have a very focussed voluminous and inspiring sound to accompany a singer songwriter as well as any other guitar player. In order to achieve this we applied the special and unique lattice bracing. No other acoustic gutar builder has used this classical guitar bracing in a steelstring guitar yet. This bracing pattern is responsible for a well-defined tone with more punch than a guitar with a regular X-bracing.To enhance this difference we have new cosmetics with wooden bindings and bridge pins. A new rosette with abalone and wood and the absence of a pickguard.The SWG-150-CE has a solid Sitka spruce top and rosewood sides and back. The rosewood give this guitar a powerful and sonorous sound. The Fishman Presys+ amplification system ensures problem-free onstage performance with a lot of tone-shaping flexibility.As all Richwood Master Series the Songwriter Series displays an excellent playability with a very comfortable neck profile.Specs:body shape : grand auditorium with cutawaybracing design : special Richwood lattice bracing mahogany back bracesscale length : 650mmnut width : 43 5mmbody length : 505mmlower bout width : 409mmbody thickness : 96/116mmtop material : solid A grade Sitka spruceback & side material : laminated rosewoodneck material : Indonesian mahoganyfingerboard material : Indian rosewoodfingerboard binding material : Indian rosewoodfingerbaord radius: 14 bridge material : Indian rosewoodtop color : naturalbody finishing : glossyneck finish : satinrosette : Indian rosewood and abalonetop purfling : 3-plyside binding : mahoganyback binding : mahoganytrussrod : active two-waytop position dots : 7mm + 5mm white pearl shellside position dots : 2mm white pearl shellfrets : 2.4*1.1mm 18% nickel silvernut & saddle material : bone 43*6mm and 72*3mmmachine head : Derjung Deluxe chromestrings : D'Addario EXP-16bridge pins : Indian rosewood with abalone dotpickguard : nostrap button : chromeelectronics : Fishman Presys +
