Easy install

Just push it on the pot shaft before putting the knob back on. No glue needed. Makes finding the sweet spot on my tone knob much easier.

Good value

Works well but edges are slightly sharp out of the package. I smoothed them down a bit before installation. Otherwise, does exactly what it says.

Looks OEM

Matches the chrome hardware perfectly on my Epiphone. You can barely tell it's an aftermarket add-on. Very satisfied with the quality.

Perfect for live gigs

Finally know where my volume is at during performances. The tab is visible enough without being distracting. Highly recommend for anyone using speed knobs.

Fitment issues

Too loose on my import guitar pots. Might work better on USA made potentiometers. Had to use a tiny bit of adhesive to keep it stable.

5 FAQ

Q: Will this scratch the finish of my guitar?

A: No, the washer sits under the knob and does not contact the guitar body finish.

Q: Does this fit standard CTS potentiometers?

A: Yes, designed for standard 6.35mm shafts commonly found on CTS and import pots.

Q: How many washers come in a pack?

A: Each order includes 4 steel washers, enough for a standard 2-volume 2-tone setup.

Q: Is this compatible with toggle switch tips?

A: No, this is specifically for potentiometer shafts under speed knobs.

Q: Do I need adhesive to keep it in place?

A: No, friction fit is usually sufficient once the knob is pressed over the washer.
