Dome Guitar Knobs


Simple and Easy to Install Standard Dome Knob


Mirror Like Finish with Comfortable Grip


Extremely Durable, Lightweight, Vivid Colors

We use a standard shaft opening that is universal for any 6mm coarse splined, fine splined or solid pot shaft. Includes a 1/8” set screw to secure the knob to the shaft. Black or Chrome Set Screw option available at checkout.

Measure your shaft size before ordering. ¼” shafts are NOT compatible with these knobs!

*All of our knobs come with a complimentary allen wrench and lint-free cotton polishing pad.


Installation is extremely SIMPLE. Just follow the instructions below. Simplicity of installation reduces pushing or pulling, scratching or damaging your instrument trying to install/remove defective, poorly designed competing knobs.

Installation Instructions:

  • Back out Set Screw Slightly to Allow Easy Placement
  • Slide Knob on Shaft to Desired Height
  • Align Set Screw with Shaft Split. (Splined Shaft Only.) Failure to properly align can result in knobs coming loose, falling off, and being lost.
  • Tighten the Set Screw. Do not over tighten to avoid stripped threads or damage to knob/shaft.

Xentric Advantage

  • Deeper shaft opening. Allows you to adjust the knob height to your preference. Competing dome knobs often bottom out on taller shafts affecting both appearance and performance.
  • Extremely light weight. Will not affect guitar balance like some heavy brass or even wooden knobs. Our standard knobs weigh 3 grams. Competition knobs can weigh ten times as much, sometimes more. This excessive weight is compounded by three or even four knobs.
  • Vibrant and varied colors
  • Very durable
  • Will not scratch or chip like many chrome or black coated knobs even if dropped.
  • Similar Hardness to hard hats required for safety on construction sites Basically indestructible under normal use.
