Located in Cortez, Colorado USA, the new Curt Mangan string factory builds over 140 packaged sets for guitar, bass, mandolin, banjo, and other instruments. Since launching the company in 2004, Curt Mangan FusionMatched strings are available in over 1, 000 USA independent retailers, 20 countries and are used by more than 800 artists. The company was founded by Curt Mangan who has a 46-year history with the guitar. He played and recorded professionally for many years, worked at and owned music stores, built and repaired guitars, taught lessons, wrote music and was Director of Sales and Marketing for one of the world's largest string companies for seventeen years. In addition to device-testing all strings, several first articles from every batch of Curt Mangan strings are also installed on instruments and then played by either Curt or the production manager to make sure they feel and sound perfect. The company works on a just-in-time production system. Depending on where you live, it's quite possible that the Curt Mangan strings you installed on your guitar today were only built last week.
