As with everything we make, for our Chrome version, we custom designed these using your feedback and produced them using chrome-plated, lightweight aluminum. They are great for swells and give that twist of the control a slightly better feel.
These are designed for use with potentiometers featuring a 1/4" solid shaft, such as those found on our Gunstreet Pots and commonly on US Spec CTS components. This item is essential when converting a guitar with metric specifications (e.g., Made in China, Made in Mexico, or Made in Japan models) to US Spec.
