The goal in developing Dogal Marchio Rosso cello strings was to create string tension very similar to gut string tension, even if their core is made using steel. Maestro Cella Luigi took on this challenge when he decided to start producing cello strings. To achieve this, Maestro Cella developed a formula for the steel with a high percentage of carbon. After more than 50 years, the same production process is still followed and the same materials and formulas are used. The Marchio Rosso cello strings have a flat chrome winding and give a powerful sound (with the right bowing technique..). The tolerances do not exceed 2/100 mm over the entire length of the string and the strings are made by hand. The string set is composed as follows:

- A string : steel core with chrome winding:
- D string : steel core with chrome winding:
- G string : steel core with chrome winding:
- C string : steel core with chrome winding.

Available in four sizes 1/10, 1/8, 1/4, 1/2 and 3/4-4/4.
