Kluson

The original Kluson® Manufacturing Company was founded in 1925 and expanded from a small machine shop by building its reputation as the music industry’s premier supplier of tuning machines, tailpieces, brackets, bushings, and other stringed instrument parts during the golden age of guitar manufacturing from the 1940s through the 1960s. That history continues today.
