This article is presented by the Southbound String Company – the first brand focused solely on providing strings specifically chosen and voiced for Cigar Box Guitars and other handmade/homemade instruments!
This chart shows you the string size to use for every pitch from double-low B (one Octave below the low B on a guitar), all the way up to High A.
Using this chart you can figure out the strings to use for pretty much any tuning you want. These strings should work for instruments with a scale length of 24.5 to 25.5 inches, with 25 inches being the middle point.
The string gauges shown below are for a “light” string set. For a “medium” set, add .002″ to the wound string sizes and .001″ to the unwound string sizes. For example, for a medium set, for low C you would want .036″ instead of .034″. For high E you’d want .011″ instead of .010″. Increase string gauges from there to move towards “heavy” sets.
