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.
Generally there is a bit of wiggle room on each pitch. If the chart calls for a .034″ and you have a .036″ it should work. A .038″ would probably work, but it would be pretty tight. A .040″ would probably break. Likewise, a .032″ would be OK but would be a bit looser. A .030″ would be noticeably looser, and .028″ would probably be too loose and flappy. A lot of it comes down to personal preference and what you decide will work for you. Looser strings means lower overall string tension, and less overall volume. Tighter strings mean more tension and volume, but also higher risk of bowed necks and broken strings.
These values are based on my own testing and experimenting of what works. I make no claims or guarantees that they will work for you – but they should.

|Range||Pitch/Note||String Size||String Type|
|Middle||C (261.63hz)||.014″||Plain Steel|
|High||A (440hz)||.008″||Plain Steel|
* Plain steel strings can be used for the Middle A and G notes, but on most guitars a wound string is used. We have had luck using a .016 unwound string instead of .018″ wound for the middle A; a .018″ unwound should work well for the middle G. Having an unwound string as the highest-pitched string can give a little extra treble twang, and also sounds smoother with a slide.
