== String Spacing == | |||
(A work in progress) | |||
The easiest way to get an 8-string acoustic guitar is to convert a 12-string guitar. This leads to a rather tight string spacing. The spacing can be slightly improved as follows: | |||
Conventional wisdom holds that there are two ways to space the strings: center-to-center and edge-to-edge. For the right hand, the latter is better than the former, because otherwise it's harder to fit one's finger between the thicker strings. Edge-to-edge spacing ensures that the gap between strings is uniform. | |||
On the left hand, if the spacing is too tight, when one frets a string and plays the neighboring string either open or fretted further back, the finger can dampen the neighboring string. Thus the important gap here is the gap between every other string. That is, between the 1st and 3rd string, between the 2nd and 4th string, etc. Center-to-center spacing results in this gap being smaller than need be for the thicker strings. Edge-to-edge spacing results in the same for the thinner strings. The ideal string spacing for the left hand makes a uniform gap, with this gap measured edge-to-edge not center-to-center. This spacing is called edge-to-next-edge. | |||
But specifying that this gap be uniform doesn't completely specify the spacing, because one could shift every other string sideways without changing these gaps. So we also require that the distance from the center of the 1st string to the nearest edge of the 2nd string be half the size of this gap. And likewise for the center of the thickest string and the nearest edge of the next-thickest string. | |||
In the next table, R1, R2, etc. is the radius of each string, and D is a constant roughly equal to 1/7th of the nut width. | |||
