The Ronroco (also spelt ronrroco) is a bass or baritone member of the charango family, with a 44–50-centimetre scale length. It was invented in 1968 by the brothers Gonzalo and Wilson Hermosa, of the group Los Kjarkas from Cochabamba, Bolivia, and spread to common usage during the 1980s. It was later in the 1990's and 2000's popularised further by Argentinian musician and composer Gustavo Santaolalla. It has 10 strings in 5 courses. They are always built from carved wood or bent sides (like modern charangos), never from an Armadillo shell (in the manner of older charangos).
