RainSong's largest body (JM) with a full-scale/14-fret neck for a loud and balanced instrument. 25.4" scale length, 14-frets clear of the body neck for full-sized playability and feel. Unidirectional carbon soundboard is RainSong's lightest, and, combined with all-carbon-fiber construction, the most responsive. Fishman Prefix+T electronics Description Product Description The Concert Series is all about Warm Tone. These are the lightest soundboards built by RainSong using unidirectional carbon. Unidirectional carbon mimics the tight grain of a fine spruce soundboard. Thus, it is not surprising that this line produces a warmer tone. The RainSong Orchestra Model is the most refined of all RainSong shapes. It is our most comfortable and intimate guitar, with an immediacy of presence that makes it a favorite with the coffee house crowd. The treble, already a breathtaking attribute of RainSongs, and the carbon sound are simply sublime in this little guitar. A crystal bell clarity, balance, superb separation of individual notes, and an expansive dynamic range make the OM one of our most individually expressive guitars
