The wider fretboard of this 10-string stereo Stick model provides more room for the fingers. Center-to-center string spacing is .350″ (0.9 cm) as opposed to .315″ (0.8 cm) on our standard 10-string Sticks. The space between the two groups of strings is also wider, at .500″ (1.3 cm) instead of the standard .430″ (1.1 cm). This instrument is meant to accommodate those musicians with larger hands and fingers, and those who want more of a guitar like string spacing. It’s a step in the direction of the SB8 (Stick Bass), which spaces all eight strings uniformly .400″ (1 cm) apart, measured from center to center of each string. The SB8 has the typical Stick stereo placement of strings into two groups of four, but the string spacing is uniform all across a single sequence of perfect fourths. The Ten-String Grand, on the other hand, preserves the wider physical gap at the center between the two groups of strings, as with other Stick type 4ths/5ths tunings.
