These are based on the original formulas developed at Guadalupe Custom Strings but with some small tweaks that I find work best. Personally, the Tenor Ukulele, is my favorite size in that tuning. The tension is perfect and the strings are responsive, sonorous, and percussive.. I've recently sourced the original material used by Francisco Gonzalez and the result is a tightly wound string with crisp sound and feel.
Available in Candy Stripe or Multicolor in both Low G (GCEA) featuring a silvered copper wound 4th string and re-entrant (gCEA).
