Good Value

Nice knob for the price. The set screw is a bit small but works well once tightened.

Perfect Size

20mm is exactly what I needed for my volume pot. The diameter gives great leverage for swells.

Solid metal construction that feels much better than the stock plastic knobs. Fits perfectly on my Strat.
