guyker CKB003 Guitar Control Knobs, 6mm Brass Dome Set, Chrome, 4-Pack

CNC-machined brass construction gives these chrome dome knobs a solid replacement for worn or discolored guitar controls. The four-piece set is made for compatible 6mm potentiometer shafts. Use them for volume or tone controls on an electric guitar or bass, or as part of a restoration or upgrade project.

Quick overview

The guyker CKB003 set combines a barrel-style dome shape with a chrome finish and brass construction. Its compact profile measures 16.2mm high and 18mm across, giving the control area a defined, coordinated look while keeping the knobs easy to reach and turn. The knurled texture supports rotary use as you adjust a control.

Four knobs are included, so the set can refresh several controls in one project rather than replacing only a single knob. That makes it practical for a guitar or bass restoration where multiple knobs are worn, dirty, or discolored. The same style can also be used for a DIY control-area update.

Quick sizing guide

Each knob has a 6mm mounting hole for a compatible potentiometer shaft. Check the shaft size and the product dimensions against the instrument before installation. The knobs measure 16.2mm in height and 18mm in outer diameter, useful reference points when matching the available space and the appearance of existing controls.

Installation depends on the shaft type. For a split pot shaft, align the knob’s set screw with the split and tighten it. For a solid shaft, tighten the screw to secure the knob. This straightforward fitting approach lets you replace individual controls or install the set as part of a broader hardware refresh.

Best use cases

These knobs are suited to replacing old, broken, dirty, or faded volume and tone controls on compatible electric guitars and basses. For example, during a restoration, the four matching chrome pieces can bring several control positions into a consistent style. They can also serve as replacement adjustment knobs for compatible amps and other musical equipment that use a 6mm potentiometer shaft.

Choose this set when you want brass knobs with a chrome finish and a dome profile. If a project only needs one replacement, a single knob may be a closer fit, this four-piece set is useful when several controls need attention together. It suits you if you’re updating a compatible instrument and want the same style across its control knobs.

Questions before you buy

Is it worth it?

For a guitar or bass project that calls for multiple matching control replacements, the CKB003 set brings together four brass, CNC-machined knobs in a chrome finish, with a dome shape and a defined 6mm fit. It’s a practical choice for restoring worn controls or giving a compatible instrument a coordinated update.
