CTS (Chicago Telephone Supply)


Founded in 1896, CTS began as Chicago Telephone Supply, producing telephones and switchboards during the early boom of communication technology. By the 1920s, CTS shifted its focus from finished products to precision electronic components, most notably high-quality carbon composition variable resistors, better known today as potentiometers.

Over the decades, CTS has grown into a global leader in electronic components, supplying industries from telecommunications to music technology. Within the guitar world, CTS is the trusted choice of leading brands like Fender, Gibson, and PRS, known for its reliable build, smooth rotation, and consistent tone control.

Whether you are upgrading or building a custom instrument, CTS potentiometers deliver long-lasting performance, precise response, and authentic feel, which is exactly what discerning players and luthiers demand.
