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 WS is a wonderfully versatile guitar. Combining the best qualities of large and small bodied guitars, this body shape is ideally suited for a variety of musical situations. A large, deep chamber gives the WS strong projection and rich bass. The narrow waist and tight upper bout allow for a ringing treble, good balance and clear definition of individual notes. Overall, the WS is impeccably balanced. The shapely curves and light weight make the WS a comfortable guitar to cradle or stand with. The extra deep cutaway encourages playing up the fretboard.

The N2 neck is a result of an extensive, long-term collaboration with the renowned artist Steve Miller and Master Luthier John Bolin. The neck design is based on a modified "U" profile that has been popular in guitars since the 1950s. While the N2 has a more substantial feel than the N1 neck, it is ergonomically sound and actually results in better transfer of string vibration energy to the soundboard. The N2 features a truss rod that is accessible from the head stock. Graphite does not warp or bow with changes in humidity and temperature. The purpose of a truss rod in the N2 is to allow customization of the relief to suit individual preferences.
