Guyker NKB-007 Guitar Control Knobs, 3-Piece Brass Top Hat Set, Bronze

Players replacing worn or dirty electric-guitar or bass control knobs can use this Guyker set to refresh the knobs used for volume and tone adjustment. It includes three bronze-finish, brass top-hat knobs.

The NKB-007 is intended for electric guitars and basses, including several Tele-, LP-, Epi-, jazz bass, and PB-style instruments. Fit depends on the potentiometer shaft, so the instrument style alone is not enough to confirm compatibility.

Would a knob replacement solve the problem, or is the control itself the issue? These parts change the knobs, not the underlying potentiometers or electronics.

Why it’s worth it

The main appeal is a straightforward replacement for old, dirty, or broken control knobs, with brass construction and a top-hat bell shape. The listed surface is designed to provide grip for adjustment, which may be useful when making quick volume or tone changes while playing. The bronze color also gives the controls a consistent visual update without requiring a broader hardware change.

Compared with replacing a full control assembly, changing only the knobs is the more focused approach when the existing controls work and the problem is limited to the knob. The set is described as suitable for both guitar and bass, but the shaft dimensions remain the deciding factor for fit.

The essentials

The package is listed as three pieces. Each knob is described for a shaft about 6 mm in diameter, with a 4.2 mm set screw. The product information also gives a total diameter of 24.92 mm and a height of 14.67 mm. These measurements can help when comparing the knobs with the space and hardware on an instrument.

The listing names Tele-, LP-, and Epi-style guitars, as well as jazz bass and PB-style basses, among the intended applications. Treat these as examples rather than a guarantee for every instrument in those families: different potentiometers may use different shaft styles or dimensions. The stated use is for volume and tone controls, not as a replacement for a switch or potentiometer.

Practical tips

Before ordering, compare your existing pot shaft with the supplied parameter drawing and check that the knob can sit correctly on it. The product details describe an approximately 6 mm hollow shaft opening and a 4.2 mm set screw, while the manufacturer description also refers to solid and split-shaft pots. That wording leaves some ambiguity about shaft style, so matching the actual dimensions is especially important with this limitation.

The set screw is part of the specified fitting design. Use the listed dimensions as a reference, and avoid assuming that a similar-looking guitar or bass automatically has the right pot. If you are replacing only one damaged knob, note that this pack is listed as three pieces.

When it makes sense

A solid pick if your existing volume or tone controls work, but their knobs are worn, dirty, or broken, and your pot dimensions match the listed fit. The three-piece set also suits someone updating several controls at once while keeping the existing electronics in place.

It might not be a great match if the shaft size or style does not correspond to the product details, or if the potentiometer itself needs replacement. In that case, checking the control hardware first is more useful than choosing knobs based only on the instrument’s model family.
