Good but Tight Fit

Quality is excellent, but the fit was very tight on my shafts. I had to push them on firmly. Once on, they are secure though.

Great Quality Feel

Solid construction and not flimsy at all. They stay in place during aggressive playing sessions. Highly recommend for any Strat or Tele build.

Perfect Fit for CTS Pots

These knobs fit my CTS potentiometers perfectly. The knurling grips well and they look exactly like the originals that came with my guitar.

Classic Look

Restored the vintage look of my bass. The black finish matches the pickguard nicely. No slipping or loosening over time.

5 FAQ

Q: How many knobs are included in one package?

A: Each package contains 4 knobs, which is enough for a standard guitar or bass control layout.

A: The outer diameter is approximately 18mm, providing a comfortable grip for volume and tone adjustments.

Q: Are these suitable for active electronics?

A: Yes, the knobs are compatible with the shafts used on pots within active electronic setups, provided the shaft is knurled.
