A Regal Touch For Your Guitar
Upgrade your instrument with a look that commands attention
Throughout history, purple has been the color of kings, queens, and rulers. It symbolized wealth, prestige, and a status reserved for the few. From ancient courts to royal banners, it’s a hue that has always stood apart. Now, you can bring that same sense of distinction to your guitar.
The Guitar Knob
This piece features a deep pearlescent purple acrylic top with a swirling, chatoyant effect. From every angle, light dances across the surface, revealing rich violet tones and subtle highlights.
Pick one up and you’ll immediately notice the weighty, substantial feel. The knurled texture along the sides ensures a confident grip every time you reach to swell the volume or shape your tone.
Glow In The Dark
A UV‑reactive indicator dot is set into the top — available in either aqua blue or green glow. The inlays are crafted in‑house to the same high standard used in our premium guitar picks.
Charge them in sunlight for a minute or two, or use a flashlight for a quick boost. Under UV blacklight, the glow comes to life instantly, and will continue to shine for hours after the light source is removed.
Fitment
These are slip‑on style knobs with a snug, secure fit — no side screw required. They are designed for “coarse” knurled potentiometers only. They will not fit fine‑spline (Imperial‑sized) pots like CTS.
To confirm fitment, remove one of your existing knobs and check the splines — they should match the coarse pattern shown in our reference image.
Dimensions
Diameter: 20 mm (0.79 in)
Height: 21 mm (0.82 in)
Each knob is sold individually.
