TonePros® under license from Kluson® has successfully combined the classic styling of the original Kluson® 3 + 3 design with the modern cutting edge functionality that TonePros® is known for. Utilizing the same footprint and mounting screw pattern, TonePros® offers you several different options to either retrofit your vintage instrument with little to no modification or upgrade your modern instrument.

This 15:1 ratio, die-cast 3 + 3 set of tuning machines has a hex-head screw-in bushing (or commonly known as a bolt bushing). It also has the classic Kluson butterbean oval shaped button. This requires a 10mm (25.64 inch) peghole for installation.
