This is the original Strumstick design. The primary key is G, also tunable down as low as C or up to A. Useable keys are C, C#, D, D#, E, F, F#, G, G#, and A. 29 1/2 long by 4 wide by 1 deep. The body and neck are Padouk (a rich red hardwood from Africa), the soundboard is Spruce, and the back is Maple. The tuning is G D G (one octave higher). The lower G is the same note as the guitar third string. The frets are placed to give a diatonic scale, with an additional flatted seventh. Pitch range is 2 1/2 octaves. The Strumstick has it's own unique sound, bright, clear, and snappy. People say it reminds them of a blend of banjo, dulcimer, and mandolin. The strings are loop end (banjo or mandolin), .023 wound, .014 plain, .010 plain. Includes a free instruction book.
