KAISH 2xK2197-V+2xK2197-T Guitar Knobs, Blue Aluminum, 1/4-Inch

If you need a coordinated set of volume and tone knobs for potentiometers with 1/4-inch shafts, this KAISH set includes four blue aluminum knobs: two for volume and two for tone. Their top-hat bell shape gives the controls a consistent look across an instrument or audio setup. Each knob uses a set screw to hold its position on the shaft.

What matters most

The set combines CNC-machined aluminum construction with a set-screw fitting, giving you a metal alternative to knobs with plastic inserts. The four-piece configuration is arranged for two volume and two tone controls, making it useful when replacing a matched set rather than changing a single knob. The blue finish also provides a clear visual accent for a guitar, bass, amplifier, preamp, or other audio equipment.

The inner diameter is 1/4 inch, and the knobs are designed for most solid-shaft, split-shaft, and D-shaft potentiometers with that shaft size. The product description lists use with many guitars, including Strat-style instruments, Yamaha, Ibanez, and Les Paul models, as well as basses and audio equipment. Compatibility depends on the potentiometer shaft fitting the stated diameter, so this is a practical choice when that measurement matches your setup.

Each knob measures 25mm across the bottom, 17mm across the top body, and 13mm high. The listed inner diameter is 6.35mm. These proportions help identify the fit and appearance before you replace existing controls or customize a project.

Practical tips

During installation, place each knob over the potentiometer shaft and tighten its set screw with the included Allen wrench. On a split-shaft potentiometer, align the set screw parallel to the split gap before tightening. This positioning helps avoid putting pressure across the split in the shaft. Once installed, the screw secures the knob in place while keeping the control accessible for regular adjustments.

Getting the most from it

For a straightforward refresh, replace the volume and tone knobs together so all four controls share the same blue finish and top-hat profile. The layout also suits a build or repair where you want to distinguish a complete set of controls from a one-knob replacement. If you are fitting them to an amplifier or other audio equipment, the same shaft-size requirement applies: the potentiometer must have a compatible 1/4-inch shaft.

Compared with choosing individual knobs one at a time, this set gives you the two-volume, two-tone arrangement in a matching style. It is especially useful when the goal is a coordinated control layout with a metal body and a screw-secured fit. A solid pick if you are replacing a full set and want the blue aluminum finish to carry across each control.

Questions before you buy

How many knobs are included, and what are they for? The set is described as two volume knobs and two tone knobs, for four knobs total.

What tool is used to tighten the set screws? An Allen wrench is included for adjusting the screws.

Can these fit a split-shaft potentiometer? They are described as compatible with most split-shaft pots that match the 1/4-inch inner diameter. Align the set screw parallel to the split gap during installation.

When it makes sense

Choose this set when you want four matching controls for a compatible guitar, bass, amplifier, or other audio device, with a blue aluminum finish and set-screw attachment. The two-volume, two-tone configuration is suited to a complete control refresh, while the stated shaft size and included Allen wrench make it easier to plan the fit and installation.
