We handle well-known CTS potentiometers from 2013. We select brass shaft for sound and line up 3 different shaft length to mount to pickguards or guitar bodies. The metric versions have been added! Most of the CTS pots in the musical instrument industry are made in the inch unit system. So even if you like the quality of the CTS pots, but if the other pots in metric are used to your instruments, when you install the CTS pots to the instruments, you will have to do some minor adjustment. In such moments, use these metric versions, and no more extra works!
