Bear claw Sitka spruce soundboard, Indian rosewood back and sides, curly koa binding (including the peghead and fretboard). This guitar has a really rich, warm sound with plenty of articulation. From Chris: "My guitar has more sustain than I've ever experienced before. It is as if it is plugged in . . . when it's not. It perfectly embodies what I was hoping for..I was playing Ramble On the other day, and I swear it sounds like more than one guitar playing at once; again the sustain is just awesome - almost like it has a natural chorus effect to it."
