Stylish and functional

Looks amazing on my custom build. The 19mm size gives it a substantial feel without being too bulky. The set screw ensures it never slips.

Perfect fit for my Stratocaster

This knob fits the splined shafts on my CTS pots perfectly. The matte black finish looks premium and matches my hardware exactly. Very happy with the purchase.

Great quality, slightly tight

The build quality is excellent and it feels solid. It was a bit tight to push onto the shaft initially, but once seated, it stays put without wobbling.

Good but color varies slightly

The knob works well and fits fine, but the black shade is slightly darker than my existing pickups. Not a dealbreaker, but worth noting.

Excellent upgrade

Replaced the cheap plastic knobs on my amp with these. The difference in feel and aesthetics is night and day. Highly recommended for DIY projects.

Solid construction

Heavy duty aluminum that doesn't feel cheap. Easy to install and provides a smooth grip for volume swells. Will buy more for my other guitars.
